Pls my fellow Nigerians, Pls advice me if you have anyway easy way of getting a US Visitor's Visa including documents to take along assuming one's friend is inviting one to come and spend some time over there. Pls links and what to do and to expect will be highly welcomed.

No Easy way!!!

my dear no short cut to america visa oh, this one no be like uk or south africa they can help you without even appearing.
all you need to do is be prayerfull, make an attemp, its a two way thing, its either you are given or denied and thats give you a chance next time you re appear. you might be luckythat the consular office his in good mood and issue a visisting visa.
this are the following strong point they watch out for.

the person inviting you is he or she financially okay to cater for you while in the state,
the you have a good job here and good financial background, i mean something concrete to convince them you will be returning back to nigeria after a short stay.

wish you and i all the best.

Check the website for documents you need and be very honest. Also when they interview always show your ties to Nigeria. make it seem unconscious.
