Evidence of work and current address for forms? Previous A number...

[zinger143 3]

So my fiancée is a taxi driver, he drives his brothers car around and gets cash. There are no records or employers, just that he is a taxi driver. He has his license that says he is a taxi driver, would that be a problem when filling out the forms?

Also, he is going to move within the month, can I put his brothers address as where he is living now? He moved apartments for my visit so we could have hot water, and will be moving at the end of the month, so I don´t want to list the current address, but I also don´t know where he is going (neither does he) and his brothers address is somewhere he visits every week and could pick up mail. I don´t want to wait a month to submit the paperwork obviously with the new address. Suggestions?

Lastly, he came to the US before, but I don´t have his A number, and they ask for it on the I-129F. Do I need that, or will it cause an RFE? Any suggestions on where I could get that number?

Is he a permanent resident or US citizen? I ask because your profile says you are filing for IR-1 but you mention I-129F which is a form for the fiancé visa, if it's a fiancé visa what you are doing he must be a US citizen, if he was a permanent resident before he can find his A number on his green card or in his naturalization certificate

I have to change it, he came up on a K-1 visa and went home (LONG STORY) and 8 years later we reunited, so he had a number for a short time 8 years ago, and now we are doing the i-129F again
