1. the letter says 'leave U.S. immediately', but does not define how long the 'immediately' means. Is 3-week OK?
2. the letter says the decision cannot be appealed, but a motion can be filed with I290B form within 30 days. Is it useful to file this form? Can I do the following: first, my parents leave USA, 2nd at the same time, file I290B. Because it does not hurt, if it works, then there will be no negative impact on future visa applications. Is this strategy OK?
Thank you very much! Happy Chinese New Year!
