Hello,
I had a question. My wife and I were married in the United States. She applied for an IR2 visa for her two minor children in the Philippines. We have not received an IL yet, however, the plan is for me to travel to the Philippines and back with them to the United States after they receive the visas. My wife cannot travel because she must attend to our newborn.
What kind of paperwork or clearance would they need to travel with me since I am not the biological father?
