Re: Jurisdiction for an International Custody and Child Support Case
What is clear is that until the child comes to the US and is here long enough to gain residency, all legal actions regarding the child will be according to VN law. There is no US limitation on you filing for custody of your child, though several other barriers may be presented. Likely you are best to wait out an appearance in the US or hire a VN lawyer.
Teach a man to fish, you feed an entire village. Give a man a fish, the village starts demanding free fish. Then they have three children who all start families and demand free fish as their right.
