Yup, totally understand but our divorce lawyer's friend (who wanted to take care of my sponsorship to 2nd wife) didn't even bring up 3 years gap once. The guy kept telling me that I should be getting married soon and just bring them the proofs and he will take care of the rest but now when I talked to him, he's like, "Oh yeah man, not sure how I missed that, you will have to wait 3 years after the first wife became PR." Which sucks big time for me.
Anyways, I am trying to think of ways to utilize this time for better. Probably look around for options of getting her to States, Mexico etc to meet in the meantime.
