Could earning income in Korea cause a problem while on F-1 status?
As an F-1 holder without work authorization, suppose I earn personal income through part-time work.
If I have that income sent to Korea, I’d like to know if this could still cause a problem.
If someone on F-1 status works and earns income, the following happens:
1. A U.S. company reports the expense on their tax filing.
2. Even if you file taxes in Korea, this is recorded as U.S. income and becomes subject to additional U.S. tax filing.
3. If receiving payment for advertising, this is possible only in the form of a company (i.e., forming a company).
4. Even if the account is in Korea, the labor is performed in the U.S.
So, strictly speaking, if USCIS becomes aware of income generated this way, it constitutes a violation of immigration law for working without authorization — regardless of which country the money is received in.
