Hello, my greencard interview is scheduled on last week of April in Michigan. I'm supposed to attend the interview with my spouse. However my spouse is currently in Arizona for her in university. The interview is scheduled on the last week of the semester and there are exams scheduled on the day already. She will need to skip the exam to be able to attend the interview with me. That will negatively affect her grades. She would be in Michigan in early May after the semester is over.
We would like to reschedule the interview to two to three weeks later if it is safe to do so. Would the reason above be good enough for USCIS to reschedule? We are afraid that USCIS may deny the request to reschedule and reject the greencard application as well. Please advise. Thank you!
