“I am on an F-1 visa and plan to day trade. Is it legal for me to day trade stocks, forex, or crypto using my own money, or trade with a prop firm? What are the immigration and tax implications I need to know about?”
The asset—stock, forex, or crypto—is not the main immigration issue; the decisive question is whether you are investing or performing business activity or compensated services. You can manage the risk by keeping personal investments separate and obtaining authorization before accepting any prop-firm arrangement.
Your answer forks according to whether you are merely investing your capital or performing business activity or services for compensation.
is the lower-risk route when you use only your capital, trade only for yourself, provide no services, receive no firm payout, and do not operate the activity as a substantial, continuous trading business. For a , IRC §864 expressly protects qualifying own-account securities trading from being treated as a U.S. trade or business, but that tax safe harbor is not an immigration safe harbor (26 USC 864(b)(2)).
Bare F-1 status does not authorize self-employment merely because you have no outside employer. Matter of Tong holds that unauthorized self-employment can be unauthorized employment, while the IRS recognizes sufficiently substantial, continuous, regular day trading as a business; do not run that business unless an authorized practical-training route covers it (Matter of Tong; IRS Topic 429).
If a pays you for trading performance, evaluations, availability, or other activity, you are performing compensated services rather than simply investing your money. Do not begin under bare F-1 status, even if the firm calls you an independent contractor or issues Form 1099-NEC (USCIS Policy Manual Vol. 7, Part B, Ch. 6; IRS Independent Contractor guidance).
can cover a prop-firm role only when the training is integral to your established curriculum and the DSO authorizes the specific training before it begins. Ordinary requires work directly related to your major, a DSO recommendation, Form I-765 approval, and a valid ; the 2010 ICE guide allows an ordinary-OPT student to own and actively operate a properly licensed degree-related business (8 CFR 214.2(f)(10); USCIS Policy Manual Vol. 2, Part F, Ch. 5; ICE OPT Policy Guidance).
can cover the activity only if the prop firm or qualifying startup is an E-Verify employer, signs and implements Form I-983, provides at least 20 hours per week, and maintains a bona fide employer-employee relationship while giving the required training. A self-directed payout account with no genuine employing entity does not meet those requirements (8 CFR 214.2(f)(10)(ii)(C); USCIS Policy Manual Vol. 2, Part F, Ch. 5).
A favorable tax classification never supplies immigration work authorization, and reporting income does not cure unauthorized employment.
These steps separate personal investing from work, secure authorization when needed, and put each type of trading income on the correct tax path.
Before placing frequent trades
Separate your personal account from any trading work
Use the account only for your own investments and retain statements showing that the capital and gains are yours. Do not describe or operate the activity as a business, solicit customers, manage other people's money, accept performance payouts, or enter a prop-firm challenge while relying only on bare F-1 status; DHS provides no numerical safe harbor for the number of trades.
Requirements
Before any CPT activity
Obtain CPT authorization for curricular prop-firm training
Give the offer and curriculum evidence to your DSO. The DSO—not USCIS—authorizes the employer, location, dates, and full- or part-time CPT in SEVIS and issues an endorsed Form I-20; CPT does not use Form I-765 or require an I-765 fee, but you cannot start before the authorized start date (8 CFR 214.2(f)(10)(i)).
Requirements
Within the OPT filing window
File for ordinary OPT if CPT does not fit
For post-completion OPT, file Form I-765 with USCIS up to 90 days before your program end date and no later than 60 days afterward, and ensure USCIS receives it within 30 days after the DSO enters the OPT recommendation. Do not perform the work until USCIS approves the application, the is valid, and its start date arrives; post-completion work must total at least 20 hours per week, and the ordinary OPT unemployment limit is 90 days (8 CFR 214.2(f)(10); USCIS Form G-1055).
Requirements
Up to 90 days before OPT expires
Meet the additional STEM OPT conditions
File the STEM Form I-765 no more than 90 days before the current EAD expires and within 60 days after the DSO's STEM recommendation. The firm signing Form I-983 must employ you and provide and supervise the training; a payout-only or self-directed prop account is not enough. STEM OPT allows 150 aggregate unemployment days when the initial 90-day OPT allowance is included (8 CFR 214.2(f)(10)(ii)(C); USCIS Policy Manual Vol. 2, Part F, Ch. 5).
Requirements
Before selecting a broker tax form
Determine your federal tax residency
During the usual first five qualifying F-1 calendar years, exclude student days from the substantial-presence test and file Form 8843. After that, apply the substantial-presence test unless the extended student exception is established. If you are a , give the broker Form W-8BEN; if you are a , use Form W-9 and report worldwide income on Form 1040.
Requirements
For each tax year traded
Report the trades and prop-firm payouts
If you are a nonresident, qualifying own-account securities trades normally fall within 26 USC 864(b)(2), but U.S. dividends generally face 30% withholding unless a treaty lowers it; qualifying U.S.-source capital gains can face 30% when you are physically present at least 183 days. File Form 1040-NR by April 15, 2027 for calendar-year 2026 if you received employee wages subject to withholding, or June 15, 2027 if you did not. If you are a resident, file Form 1040 by April 15, 2027, report capital-asset stock and crypto dispositions on Form 8949 and Schedule D, and generally treat section 988 forex gains or losses as ordinary. A Form 1099-NEC prop payout normally goes on Schedule C; residents generally owe self-employment tax once net self-employment earnings reach $400, while nonresidents generally do not unless a social-security agreement applies.
Requirements
You are not the first to go through this. Here is how it went for others who asked the same thing.
u/JoeyOOTSPr/taxMar 29, 2026
The controlling material comes from DHS regulations, USCIS and ICE guidance, a Justice Department immigration decision, the Internal Revenue Code, and IRS forms and instructions.
USCIS Policy Manual Vol. 7 Pt. B Ch. 6
USCIS defines unauthorized employment broadly enough to cover services performed without the required permission.
Chapter 6, Section B
Unauthorized employment is any service or labor performed for an employer within the United States by an alien who is not authorized by the INA or USCIS to accept employment or who exceeds the scope or period of the alien's employment authorization.
Matter of Tong, 16 I&N Dec. 593 (BIA 1978)
The immigration appeals authority expressly recognizes that self-employment can be unauthorized employment.
16 I&N Dec. 593
Unauthorized self-employment as a used car dealer is "unauthorized employment" within the purview of section 245(c) of the Immigration and Nationality Act (8 U.S.C. 1255(c)) and precluded adjustment of status.
8 CFR 214.2(f)(10)
The F-1 regulation limits practical training to major-related positions and requires CPT to be integral to the curriculum.
(f)(10)(i)-(ii)
An eligible student may request employment authorization for practical training in a position that is directly related to their major area of study. An F-1 student may be authorized by the DSO to participate in a curricular practical training program that is an integral part of an established curriculum.
USCIS Policy Manual Vol. 2 Pt. F Ch. 5
A DSO recommendation alone is not OPT work authorization; USCIS authorization and a valid EAD are required.
Chapter 5, Section C
Each period of OPT must be recommended by the DSO and authorized by USCIS, as shown by a valid EAD.
ICE OPT Policy Guidance 1004-03
ICE's ordinary-OPT guidance recognizes degree-related self-employment with evidence of licenses and active operation.
Section 7.2.1
Self-employed business owner. A student on OPT may start a business and be self-employed. The student must be able to prove that he or she has the proper business licenses and is actively engaged in a business related to the student's degree program.
USCIS Policy Manual Vol. 2 Pt. F Ch. 5
Current STEM OPT requires a genuine employing entity that provides the training and signs Form I-983.
Chapter 5, STEM OPT employer requirements
To employ a STEM OPT F-1 student, an employer must have and maintain a bona fide employer-employee relationship with the student. The employer that signs the Form I-983 must be the same entity that provides the practical training experience to the student.
USCIS Policy Manual Vol. 7 Pt. B Ch. 8
INA 245(k) is a narrow adjustment exception for certain employment-based applicants, not permission to work.
Chapter 8, Section C
This exemption applies to an applicant who has not failed to maintain a lawful status, engaged in unauthorized employment, or violated the terms and conditions of his or her admission for an aggregate period exceeding 180 days.
26 USC 864(b)(2)
Federal tax law generally excludes qualifying own-account securities trading from a nonresident's U.S. trade or business, with dealer and commodity limitations.
(b)(2)(A)(ii) and (B)(iii)
Trading in stocks or securities for the taxpayer's own account, whether by the taxpayer or his employees or through a resident broker, commission agent, custodian, or other agent, and whether or not any such employee or agent has discretionary authority to make decisions in effecting the transactions. This clause shall not apply in the case of a dealer in stocks or securities. Clauses (i) and (ii) shall apply only if the commodities are of a kind customarily dealt in on an organized commodity exchange and if the transaction is of a kind customarily consummated at such place.
IRS Nonresident Student Capital-Gains Guidance
The nonresident capital-gains 183-day rule is separate from the substantial-presence test used to determine tax residency.
A flat tax of 30 percent (or lower treaty) rate is imposed on U.S. source capital gains in the hands of nonresident individuals present in the U.S. for 183 days or more during the taxable year. This 183-day rule bears no relation to the 183-day rule under the substantial presence test of Internal Revenue Code (IRC) 7701(b)(3).
Form 8843
F-1 student exempt-individual years are calendar years, and the ordinary student exclusion becomes restricted after five.
Part III
Even if you meet these requirements, you can't exclude days of presence in 2025 as a student if you were exempt as a teacher, trainee, or student for any part of more than 5 calendar years unless you establish that you don't intend to reside permanently in the United States.
IRS Taxation of Resident Aliens
A resident alien files Form 1040 and reports worldwide income like a U.S. citizen.
A resident alien's income is generally subject to tax in the same manner as a U.S. citizen. If you are a resident alien, you must report all interest, dividends, wages, or other compensation for services, income from rental property or royalties, and other types of income on your U.S. tax return. You must report these amounts whether from sources within or outside the United States. Resident aliens file Form 1040 like U.S. citizens.
IRS Topic 429
The IRS distinguishes a securities trader business from ordinary investment activity by purpose, substantiality, continuity, and regularity.
Special rules apply if you're a trader in securities, in the business of buying and selling securities for your own account. To be engaged in business as a trader in securities, you must meet all of the following conditions: You must seek to profit from daily market movements in the prices of securities and not from dividends, interest, or capital appreciation; Your activity must be substantial; and You must carry on the activity with continuity and regularity.
IRS Digital Assets Guidance
Crypto and other digital assets held as capital assets are treated as property and dispositions go on Form 8949.
For U.S. tax purposes, digital assets are considered property, not currency. If you sold, exchanged or otherwise disposed of a digital asset you held as a capital asset, use Form 8949, Sales and Other Dispositions of Capital Assets.
26 USC 988
Foreign-currency gains and losses covered by section 988 are generally ordinary rather than capital.
(a)(1)(A)
Except as otherwise provided in this section, any foreign currency gain or loss attributable to a section 988 transaction shall be computed separately and treated as ordinary income or loss (as the case may be).
IRS Independent Contractor Guidance
A prop-firm Form 1099-NEC normally means the payer is treating the payout as self-employment compensation.
If payment for services you provided is listed on Form 1099-NEC, Nonemployee Compensation, the payer is treating you as self-employed, also referred to as an independent contractor.
IRS Publication 519
Most nonresident aliens do not owe U.S. self-employment tax, although an applicable social-security agreement can change that result.
Self-Employment Tax
Nonresident aliens are not subject to self-employment tax unless an international social security agreement in effect determines that they are covered under the U.S. social security system.
Instructions for Form 1040-NR
Form 1040-NR generally has an April-equivalent deadline for people with withheld wages and a June-equivalent deadline otherwise.
When To File
If you were an employee and received wages subject to U.S. income tax withholding, file Form 1040-NR by the 15th day of the 4th month after your tax year ends. If you didn't receive wages as an employee subject to U.S. income tax withholding, file Form 1040-NR by the 15th day of the 6th month after your tax year ends.
Instructions for Form W-8BEN
A nonresident generally documents foreign status to a broker or other withholding agent with Form W-8BEN.
Who Must Provide Form W-8BEN
You must give Form W-8BEN to the withholding agent or payer if you are a nonresident alien who is the beneficial owner of an amount subject to withholding, or if you are an account holder of an FFI documenting yourself as a nonresident alien.
