Is my father a US citizen
Is my father a US citizen if he was born in the UK. His parents moved to the U.S. when he was 2 years of age. His father (but not mother) became a U.S. citizen when my father (his son) was 7 years old.
My father grew up entirely in the U.S. and was married to a U.S. citizen for twenty years.
He never applied for citizenship. He has a SS#. He is terminal disabled, hospitalized, and receiving medicare (medicaid).
How (where) do I ensure that he is a US citizen, And could my application for A UK passport (dual citizenship) possibly affect his receiving medicaid.
Thanks.
