No. "May I see your passport, please?" is probably the best way to say it. "For" is not used with "request": you can request someone's passport, or you can request that someone show you his passport. And since requesting is already asking for something, it is redundant to use both "may I" and "request".
Yes, it is correct to say "this is regarding your request" when referring to a specific request or inquiry made by someone. It is a professional and clear way to acknowledge the subject of communication.
