Born abroad with one parent acquiring US citizenship
If one of your parents became a US citizen after you were born, you may acquire citizenship through that parent. The rules are different depending on when you were born, but most people have to show that they were less than 18 years old when their parent became a citizen,and that they were living in the US as a lawful permanent resident at the time.
Adopted by a US citizens
If you were adopted by a US citizen, you may have automatically acquired citizenship through your adoptive parent. Generally, an adoptee born after 1982 is a citizen if they were admitted to the US as a lawful permanent resident and lived in the US with the adoptive US citizen parent.
