Deductions & credits

So, just to clarify things up.

 

We can file MJF, because

She has file all of her taxes for the previous years as non resident.

She has a social security card and a driver license. Also, she is on my new lease we signed this month. 

 

She had a Visa, J1 but it expired on June 26th this year.but we got married on the 18th of June. So, she has been staying here without a visa,but we are sending out the paperwork to apply for green card / adjustments of status this year.

 

Based on all of that. Can I still file as MJF? Also, if I was to file that way. For her work as an Au pair for 5 months this year. Do I need to put that on the filing as independent (self employed)? Or how do I want to file that part of her money. She hasn't worked since she completed her contract with her host family Au pair. I have been financially supporting both of us.
