I am a PhD student currently in the US on an F1-Visa. I want to invite a friend, who is currently not employed. He also does not have sufficient funds, so I am willing to cover all the expenses involved. He stays with his parents.
He is planning an art exhibition in a few months and would like to tour US to draw inspiration from.
I have the invitation letter, affidavit of support(I-134), a formal letter addressed to the consulate and my bank/university salary statements ready. However given his unemployed status, I am a bit skeptical about procuring a visa.
What other documents would possibly increase the chances of getting a B2-Visa?
Is it okay to establish home ties by stating that my friend is bound to return given he has a scheduled art exhibition back home?
