Hi I'm married to a us citizen, currently still F-1 but legal residence papperwork has been sobmited, can I claim credit for a dependent besides my wife on my income tax? Will this geopardize my current process ?thanks

You can file joint return as residents.

Or you can file nonresident tax return on F-1. On nonresident tax return, you can not claim dependent.

We REALLY need to know from which country he originated, because some non-residents CAN claim their spouses as dependents on the non-resident alien return.

I'm from mexico, now I'm sure I can claim dependents filling jointly with my american wife, but will this jeopardize my residenci process with DHS?

Filing jointly with your American wife will in no way jeopardize your standing with the Department of Homeland Security.

Such a filing is legally permitted under the IRS regulations.
