If I (US citizen) wish to sponsor a family friend from Nepal in a "US VISITOR VISA", what supporting documents do I need to present at the US consulate Office in KTM? I can think of "Affidavit of Support (INS form I-136) and a job letter…..are there anything else ? ...& what sort of documents will he (family friend) have to provide? Your help is deeply appreciated. Rgds, sk
