If the father is legal, so are his children who were born here. However, if he had gone through proper channels when he married his wife, this would not have happened. My SIL is a Filipina, (now a US citizen) and when my brother married her in the Philippines, he had to come home without her, as they had to go through legal immigration policies before she could enter the States.
My wife had to leave the U.S. to be able to immigrate back in. It was very costly for us. No sympathy here. VERY difficult. I could sure work for and provide priceless assistance to Mr. Homan. He just doesn’t know it.
