No, working while on a tourist visa (B-1/B-2) is not allowed even if it's for a foreign company.

The U.S. government defines “work” broadly, and remote work counts as unauthorized employment.

Some types of business-related activities are allowed on a B-1 visa like meetings or training, but not actual work.

If you want to work remotely while in the U.S., it’s safer to apply for a proper work or freelance visa.
