I have a good friend who is visiting from Thailand on a B2 visa. He is wanting to file an extension (he totally underestimated how cold it gets here in the winter and wants to see some outdoor stuff). He works in hotel management and his employer is encouraging him to stay, as it is allowing him to learn US customs and learn English, a huge benefit at his job. Anyway, he came here with a large amount of cash to support himself. He has free food and lodging, any suggestions on how to prove financial responsibility for extending visa? If I had realized what he was doing, I’d have helped him open a bank account or make other arrangements. But, I’m afraid it’d look kinda shady to do so shortly before applying for extension. Thanks!
