non resident J1 and resident J2 filling together

Hello all,

I have a J1 research scholar visa. I am in USA since december 2015. I was considered non resident in 2019 because as J1 you are non resident for two years in the last seven years (i came in US as J1 also in 2012 for 6 months). 

My wife came with me from december 2015. She has a working permit since 2016. So she is considered resident.

I just want to make sure, can we fill jointly if we include the letter to ask IRS to treat me as resident with my wife?

 

thank you
