Problem with my name when filing for my wife's visa

[ppb 0]

Hi. My name's Peter and this is my first post on this site.

I have what may potentially be a problem for me when I apply for a visa for my Vietnamese spouse:

My name is "Peter T___ P____ B____" (name hidden due to internet paranoia). The "T___ P___" is my middle name.

My passport has "Peter T. P____ B____".

I generally use just "Peter P____ B____".

My marriage paperwork in Vietnam has all three of the above. My Vietnamese marriage license has "Peter P____ B____".

My question is: Will this be a problem for me when I apply over here in the US and at the Consulate in Vietnam? The officials at the So Thu Phap made a small fuss over the "T." and my middle name in general.

Has anyone encountered, had or heard about this problem before? These are all my names. They also have my SSN, passport #, date of birth and address. That should be enough to verify my identity.

What can I do to avoid or alleviate this problem? I thought about hiring a lawyer, even though I am confident in my ability to do the paperwork myself.

Thanks in advance.

Peter
