He is a Russian citizen lives in China on an M-visa (business visa), and previously studied in a Chinese college. He is gapping a year from college to do business in China. I am an F-1 visa holder here in the United States.
He is currently self-employed, has real estate back in Russia, but no much of money on his bank account. I am going to cover all his travel expense here (as sponsor on document).
I wish to invite him over for a summer vacation, but we have been told by many people he's chance to get denied is very high. What should we do to increase his chance to get the B2 visa?
Should we hide our relationship? Really wish to see him but I can't go to China due to my study. then how can we explain this sponsorship?
