My first semester, I was enrolled for 12 credit hours and subsequent semester 11 credit hours till my 27th birth day. I was always in F1 status until graduate. Financial reason I was not able to take 12 credit hours per semester. I became permanent resident at the age of 42. I didn’t register with selective service also never knew anything at that time and never receive any enrollment information from Selective service. Now what is the consequence for not enrolled with selective service? According to selective service F1 student don’t require enrollment. Can I ask Selective service for an exempt status letter? Is this will be an issue? I am trying to get federal financial assistance for Post graduate studies which requires Selective service enrollment. Comment , Advice or suggestion?
