When submitting an i-130 and an i-485 simultaneously, they require similar supporting documents - does this mean that I will need to send two copies of a birth certificate for example or will one suffice for the two? Similarly, when attaching a check, is it better to give individual checks for each document or will one check with the accumulated fee be ok? Thanks in advance.

Thanks, Boiler. In full, I've been on a J-1 for a year then got a H-1B, but that company has gone under and not I'm in a position where I have been married to a USC but not sure which decision is smarter to make. Particularly, I want to know if I can submit the required documents (i-130, i-131, i-485, i-765, and i-864) while the H-1B amendment is processing. will this mess things up?

I got married, and I'm applying for a work permit. I don't think they'll wait 90 days to process, is it possible to work on H-1B and then apply for a work permit after I join on pending H-1B amendment with a company or wait out the 90 days?
