I plan to apply for my first reentry permit within the next few months. I cannot stay for the biometrics appointment but I plan to return for it. The instructions for I-131 stay that the application would be considered abandoned if you leave the US before the biometrics. My lawyer similarly told me that I need to stay until after the biometrics. I am still really hoping to not have to stay, as it would be very difficult. I would greatly appreciate if anybody could share their knowledge and experiences.
