Thanks a lot for this valuable information.
We are in a very similar situation and we have a question if you don't mind.
Do you know how to use the US-France tax treaty, article 29, paragraph 3(b) that you mentioned in IRS form 1040?
Because of the non-exemption of days of presence after 2 years, we can't file with form 1040NR anymore, but still, a big part of our third year falls into the 2 years period after our arrival as J1/J2.
