As a F1 visa applicant and after more than three months waiting for clearance, I was surprisingly recognized inadmissible for security reasons according to Section 212 (a)(3)(A). They referred me to Form DSL-851A for further details, which I've not yet found it on the web. The only suspicion I have is my military service record which is an indispensable obligation in my home country (Iran) for all male citizens. My question is that if I'll be never issued a US visa or I can reapply say at other US embassy? In the latter case if there is any (passing of) time requirement or further documents to be acquitted?
Any kind guides is highly appreciated in advance,
