“I'm on F-1 STEM OPT and a nonresident alien for tax purposes looking to open a brokerage account. Which broker allows me to sign up with a W-8BEN, issues a proper 1042-S, lets me keep my account if I move abroad, and makes it easy to switch to a W-9 when my tax status changes?”
You do not need to choose a W-9 just because you live in the United States on STEM OPT: the controlling question is your U.S. tax status. The part no broker can promise without your destination is uninterrupted overseas account access.
IBKR offers the documented tax-form and reporting route, while your eventual destination determines whether its overseas-account route remains available.
IBKR expressly includes U.S.-based F-1 students in its guidance, describes reporting for covered U.S.-source income, and provides an individual-account Tax Forms editing screen for a later . Its relocation policy permits retention when it can serve the destination, subject to a possible new application and transfer.

If your destination is a country where sanctions prohibit IBKR from doing business, its published keep-your-account promise does not apply. This branch cannot be decided for you without the destination. [IBKR relocation policy](https://www.interactivebrokers.com/campus/trading-lessons/trading-overseas-with-ibkr/)
An allowed move can still require a new application and a manual transfer of eligible assets.
These actions establish the correct tax certification now and keep your IBKR account records current through a later move or tax-status change.
Before applying
Gather your identity, address, and tax details
IBKR lists identification and residential-address evidence for an individual application at https://www.interactivebrokers.com/en/general/what-you-need-inv.php. For W-8BEN line 6a, the IRS sets out when a foreign tax identification number is required; line 6b covers the stated no-number exception at https://www.irs.gov/instructions/iw8ben.

IBKR Trading Overseas guidance
IBKR's account-retention policy depends on its ability to serve the new country.
Relocating abroad
If you relocate to a different country, you will be able to retain your account as long as you are not moving to a country that IBKR is prohibited from transacting business in due to government sanctions.
IBKR Trading Overseas guidance
Account retention does not guarantee that no new application or transfer is needed.
Relocating abroad
However, even if relocating to a permissible country, you may be required to initiate a new application and request a manual transfer of eligible assets once your new application has been approved.
IBKR Trading Overseas guidance
The account-migration requirement cannot be fixed without both countries.
Relocating abroad
Whether this step will be required depends upon the country you were residing in and the one that you are moving to as IBKR maintains multiple entities each of which has been formed to carry client accounts based upon local regulatory requirements and IBKR policies.
