Since I'm a non resident alien, I couldn't use turbotax to file my tax refund electronically and I had to mail it physically. So I "sent" it on 4/15, hours before the last pickup using USPS first class mail. However, I just found out that it was returned to me for reasons I don't know yet as it doesn't even say "Return to Sender" on the envelope. I guess I'm done for and will get deported back or something. Is there anything I can do to prevent that...?
