US B1 tourist visa [closed]

My boyfriend will be applying for a tourist visa to come visit me in the US for two weeks. He lives in the UK but he's from Poland so not part of the Visa Waiver program. Is a letter from his employer and 3 pay stubs sufficient? What other information should he take?

On the "address you intend to stay," would it be best to be honest and put my home address or a hotel? Any recommendations would be appreciated. Should he mention he is visiting a girlfriend or say that he’s renting a room? Is it necessary to take a bank statement?
