Hey can someone tell me the procedure at the airport ?

Hey guys, I had my exemption approved but the problem is that I made another application with no evidence before this application with a later dare . What if that one gets rejected, does it wipe out the one that is approved already ?

Hey , I got my approval yesterday however I needed to postpone it for 2-3 weeks. Will the exemption be valid by that time. How long does the exemption is valid for?
