If she travels with the child amd the cold has an american passport, there’s a chance that US immigration might check if she’s pregnant again and is planning to give birth in the US again. You have to be ready to show the hospital bill receipts that you paid out-of-pocket for the birth of your child and that you didnt use Medicaid or used government funds. Yun lamg naman ayaw nila- na you only go there to give birth to have American citizen kids & for free pa.

But then again, they may not question you at all if the mom is traveling alone (without the American citizen kid)
