In the context of applying for naturalization in the United States, generally, a lawful permanent resident (LPR) must meet specific residency requirements. The standard requirement is that applicants must have been a lawful permanent resident for at least 5 years (60 months). However, if they are married to a U.S. citizen, they can apply after 3 years (36 months) of permanent residence.
Given these details, the following individuals can apply for naturalization based on the information provided:
- A lawful permanent resident who has lived in the US for 36 months (if married to a U.S. citizen).
- A lawful permanent resident who has lived in the US for 60 months (qualifies under the general rule).
The ones who cannot apply based on the typical requirements are:
- A lawful permanent resident who has lived in the US for 18 months.
- A lawful permanent resident who has lived in the US for 48 months.
Thus, the answers include:
- A lawful permanent resident who has lived in the US for 36 months (if married to a U.S. citizen).
- A lawful permanent resident who has lived in the US for 60 months.
