Replying to Work/resident Visa Mexico questions

I may be selected for a long term (2 year) work assignment in Mexico. I want to know what visa or visas I will require to apply for to do this. I know after I am selected I will find out but I have reason to want to find out before hand.
I already have a job with said company.
I would be taking the same position but it may be considered a new position in Mexico to the government.
Would I need a temporary resident visa?
Would I need a work visa FM2 or H1B?
Both? All?

Basically I want to know because I do not have access to my transcripts because I'm a dead beat that didn't pay my last semesters bill. I saw you need transcripts for the work visas.

Don't tell me not to go to Mexico. It's in a safe area and for a lot of money and will benefit me greatly.

Learn me on what I will need.
