I am a F-1 Student, just last week a local company needs a Chinese speaker to verify their company brochure in chinese version. I went there and spent about 1 hour.
They paid me in check and i gave them my SSN number.
现在我突然意识到身份问题，据说我这样查出来后就要被驱逐出境.
有没有什么补救的办法？i can return the check and said my work is volunteer work. But the check is issued and sent to me already. Is there still a record? Does this affect the later Green card application?
先谢谢大家了，真的好怕!
