My deceased Cuban father had an US citizenship, is there any benefit for me?
<p>My father born in Havana, Cuba in the 40's and in '56 he immigrated to the US. I have a card of that time that says &quot;This is to certify that was admitted to the United States as an immigrant on 9/22/56 and has been duly registered according to law. Commissioner of Immigration and Naturalization&quot;.</p>
<p>He passed in 1984, in Havana. My question is: I, as legit son of his born in marriage, do I have any benefits since he was an US citizen? Can I apply for an US Visa and later apply for citizenship? I have no clue whatsoever.</p>

<p>I assume that you were not born in the United States, and that your mother was/is not a US citizen. If these assumptions are incorrect, the answer below does not apply.</p>
<p>A child born outside the United States to a US citizen and a non-US citizen will be a US citizen so long as the parent spent a certain amount of time physically present in the United States. For a child born before 1986 to gain US citizenship through a single parent, that parent would have had to spend 10 years total in the USA, of which at least 5 years were after the parent’s 14th birthday. So if your father was a citizen and lived in the US until at least 1966 or his 19th birthday (whichever was later), you would be a US citizen.</p>
<p>However, the document you describe does not prove that your father was a US citizen. Instead, it only proves that your father was admitted to the US as an permanent resident (a so-called “green card”). If your father did become a citizen, he would have received a  Certificate of Naturalization. This would be necessary to prove your father’s US citizenship and, by extension, yours.</p>
