From my experience...one is most likely to be given a visitation visa if one is invited by someone in the United State's

military. Because the invitation later would include the official command's letter head which would go a long way for

the filing and interview process. The U.S military personals are highly respected and generally viewed as outstanding

individuals...so often at times visas are granted to people who do not qualify out of respect for the services member.

But the visitation has to be for a specific event: wedding, death of a close family member, or something along the line

of a momentous life changing situation or event. Going through this route will almost guarantee you a visa...unless you

been denied before then i cant say anything for that one. So Chalay if you know anyone in the U.S

military...giving them a call sounds good right about now...

What document are required by the invitee? A friend from USA is inviting my friend here in Nigeria to come over...he sent invitation letter and statement of account and national I'd card....is that all that is needed?
