I am a US citizen living in the UK on ILR visa. I have recently had a baby in July 2021. I have been unable to get an appointment at the US embassy to register his birth (CRBA) or apply for his first passport due to limited appointments (I check every day). He has his UK birth certificate and UK passport. We are flying to US in December.
Will he be turned away at airport if he enters the US with UK passport and ESTA?
Is he still considered a US citizen even though his birth is not yet registered via the CRBA? He hasn't yet claimed citizenship?
Wording on Embassy regarding child entering US with foreign passport is 'highly recommended' that US passport is used. Seems like a grey area. Does anybody have experience with this?
