[immihelp]

Hello

Thanks for your great website and useful guidance. We are a Rock band in Iran and Tony Bon Jovi's production want to invite us to US for an interview and recording. I just want to know if you can send me a sample invitation,or a an official format. Cause they should send me an invitation and they're waiting for my reply, i should send them a sample invitation or an official format to fill and send back to me. I'll be appreciated if you can help me.

Thank you very much.
