No—you do not need to switch from ordinary Medi-Cal before your interview, and that enrollment itself cannot be used against your already-filed F4 I-485.
“I am adjusting status under the F4 family-based category and just completed biometrics. I am legally in the US and currently enrolled in Medi-Cal. Should I switch to private health insurance before my I-485 interview, and could being enrolled in Medi-Cal negatively affect my I-485 approval?”
Summary
Completing biometrics means your I-485 was already filed before the September 18, 2026 transition date, so the 2022 public-charge criteria continue to govern it. Under those criteria, ordinary Medi-Cal is excluded; your practical focus should be a complete, sufficient Form I-864.
Your answer turns on what Medi-Cal paid for—not on whether your interview happens before or after September 18, 2026.
Medi-Cal is California’s Medicaid program. Under 8 CFR 212.22(a)(3) and current USCIS Policy Manual Vol. 8, Part G, Ch. 7, ordinary Medicaid and home- and community-based services are not considered in the decision; only Medicaid-funded is the exception. For this I-485 issue, you may keep ordinary Medi-Cal.
Private insurance is not a required substitute for ordinary Medi-Cal under the rule governing your already-filed case. Form I-485’s instructions generally require no initial public-charge evidence, and changing insurance does not turn excluded Medi-Cal coverage into a relevant factor.
If Medi-Cal paid for a long nursing-facility or mental-health-institution stay, prepare the dates, duration, reason, and any evidence that the institutionalization violated your rights. USCIS may weigh that history, but the Policy Manual says it cannot by itself establish that you are likely to become a .
The July 20, 2026 Federal Register final rule controls the transition: an accepted I-485 filed before September 18 remains under the 2022 criteria while pending.

Next steps
These steps protect your health coverage while focusing your interview preparation on the issues USCIS may actually consider.
Now
Identify the kind of Medi-Cal services you received
Separate ordinary coverage—such as clinic care, emergency care, short rehabilitation, or home- and community-based services—from Medicaid-funded long-term residence in a nursing facility or mental-health institution. Only the latter category enters the public-charge analysis for this case.
Before the interview
Keep ordinary Medi-Cal if you need it
Do not cancel it or buy private insurance solely for the I-485. Under 8 CFR 212.22(a)(3), USCIS may not consider ordinary Medicaid, and the I-485 instructions do not require initial private-insurance evidence.
Before the interview
Verify the filed Form I-864 package
An F4 applicant requires Form I-864. The petitioner normally must show income of at least 125% of the current Federal Poverty Guidelines for the correct household size; a joint sponsor may qualify independently if needed. A missing required affidavit results in I-485 denial.
Requirements
Only if Medi-Cal funded a long institutional stay
Prepare an explanation only if long-term care applies
USCIS weighs the amount, duration, and recency of long-term institutionalization in the full circumstances. It excludes short rehabilitation, intermittent stays, home- and community-based services, and incarceration; even qualifying long-term care is not enough by itself for a public-charge finding.

Legal sources
This answer relies on the current federal regulation, USCIS Policy Manual and form instructions, the July 20, 2026 DHS final rule, and California DHCS guidance.
California DHCS Medi-Cal Resources
California’s health department confirms that Medi-Cal is the state’s Medicaid program, so the federal Medicaid rule applies to this coverage.
Medi-Cal is California's Medicaid program.
8 CFR 212.22(a)(3)
The current federal regulation excludes ordinary Medicaid from public-charge consideration and preserves only the long-term institutional-services exception.
§ 212.22(a)(3)
DHS will not consider receipt of, or certification or approval for future receipt of, public benefits not referenced in § 212.21(b) and (c), such as Supplemental Nutrition Assistance Program (SNAP) or other nutrition programs, Children's Health Insurance Program (CHIP), Medicaid (other than for long-term use of institutional services under section 1905(a) of the Social Security Act), housing benefits, any benefits related to immunizations or testing for communicable diseases, or other supplemental or special-purpose benefits.
USCIS Policy Manual Vol. 8 Pt. G Ch. 7
USCIS confirms that ordinary Medicaid services, including home- and community-based services, are outside the public-charge determination.
Chapter 7(C), Long-term Institutionalization at Government Expense
Long-term institutionalization at government expense is the only category of Medicaid-funded services (limited to institutional services provided under section 1905(a) of the Social Security Act) considered in a public charge inadmissibility determination. No other services paid for by Medicaid, including home and community-based services (HCBS), and no services provided under the Children’s Health Insurance Program (CHIP), are considered as long-term institutionalization at government expense.
USCIS Policy Manual Vol. 8 Pt. G Ch. 7
Even a qualifying government-funded long-term institutional stay is only one factor and is not an automatic denial.
Chapter 7(C), Long-term Institutionalization at Government Expense
In all circumstances, current and/or past long-term institutionalization at government expense is not alone a sufficient basis to determine that an applicant is likely at any time to become a public charge. Rather, it is one consideration in the totality of the circumstances.
Form I-485 Instructions (01/20/25)
The I-485 asks about only the benefit categories the 2022 rule permits USCIS to consider—not ordinary Medi-Cal.
Part 9, Items 63–66, page 8
NOTE: Item Numbers 63. - 66. are only asking about public benefits (in other words, public cash assistance for income maintenance and long-term institutionalization at government expense) you received in the past or are currently receiving at the time the Form I-485 is filed, and where you were/are a listed beneficiary.
Form I-485 Instructions (01/20/25)
USCIS generally does not require private-insurance or other initial public-charge proof and will request evidence if needed.
Evidence Relating to the Public Charge Ground of Inadmissibility, page 16
Applicants, with one exception, are not required to provide any initial evidence relating to the public charge ground of inadmissibility with their adjustment of status application. If USCIS requires additional evidence to determine if you are inadmissible under the public charge ground of inadmissibility, it will issue a Request for Evidence and consider all evidence that you provide in response.
Form I-485 Instructions (01/20/25)
For this F4 case, a sufficient Form I-864 is a real approval requirement, unlike private health insurance.
Affidavit of Support Under Section 213A of the INA, page 16
The Affidavit of Support Under Section 213A of the INA is required for most family-based intending immigrants and some employment-based intending immigrants to show that they have adequate means of financial support and are not likely to become a public charge. Failure to submit an Affidavit of Support Under Section 213A of the INA (Form I-864 or I-864EZ), when required, will result in a denial of your Form I-485.
Form I-864 Instructions (10/17/24)
F4 applicants need the petitioner’s I-864, normally supported by income at least 125% of the applicable poverty guideline.
Who Needs to Submit Form I-864? pages 1–2; What Are the Income Requirements? page 14
All family-based preference immigrants (unmarried sons and daughters of U.S. citizens, spouses and unmarried sons and daughters of lawful permanent residents, married sons and daughters of U.S. citizens, and brothers and sisters of U.S. citizens 21 years of age and older); To qualify as a sponsor, you must demonstrate that your income is at least 125 percent of the current Federal Poverty Guidelines for your household size.
91 FR 45324 (2026 Final Rule)
The 2026 rescission does not change the governing rule for this already-filed and accepted I-485, even if it remains pending after September 18.
DATES; Implementation, 91 FR 45324, 45414
The final rule is effective on September 18, 2026. Applications for admission made before that date and applications for adjustment of status filed with USCIS that were postmarked (or electronically filed) before the effective date and accepted by USCIS pursuant to 8 CFR 103.2(a)(1) and (a)(2), and are pending on the effective date will be adjudicated under the criteria set forth in the 2022 Final Rule.
These are the official rules as published on the cited dates; rules and forms can change.
