My dad (PR status) has requested a travel document and received a letter of non-compliancy (for less than 2 years out of last 5 years). He was offered to appeal the decision and he has not filed an appeal and his 60 days window for appeal has already passed. On the other hand he received a RX-1 visa which is still valid. Now my question is whether he can use this still valid RX-1 visa to come here and visit my family?
