My best friend who is like a sister to me came over to the usa with her husband under his work visa. They were married 22 years and then he left her and their two boys for another woman who he subsequently married and is now here with a green card. He did not reapply for the boys visas when he divorced the mom and has refused to do so even all these years later. The boys were born in canada but came here at the ages of 1 and 3. They have no family in canada to return to and are now both over 18. The mom is now married to an american but sadly although she is, her husband of a year just lost his job and she has been diagnosed w stage 4 breast cancer. We are trying to see if there is anyway to help the boys and releave their mothers mind so that she can deal w the cancer and possible death. Can anyone tell me what can be done?
