What would US diplomats in the UK do a British woman gives birth to a child and she makes clear that she does not want her child to be a US citizen because of the IRS taxes and does not want her child taken out the UK and Ireland and does not want her child to visit the USA before age 18 for child custody reasons.
A child who is a US citizen and resides outside the US may be subject to US tax laws, including reporting requirements and potential tax liabilities, as mentioned earlier. This is the main reason why many children born outside the USA to an American parent do not want to become a US citizen but will claim citizen ship of country of birth.
