How long does naturalization take?

Most applicants must be LPRs for at least 5 years (3 years if married to a U.S. citizen). Processing times vary by [def:uscis|USCIS] office [§ 8 U.S.C. 1427].

What happens during the naturalization interview?

A USCIS officer reviews your N-400 application, tests your English ability (reading, writing, speaking), and administers a civics test (6 of 10 questions correct to pass [§ 8 C.F.R. 312.1]). You will be asked about your background, travel, and moral character.

Can a criminal record prevent naturalization?

Some criminal convictions permanently bar naturalization (aggravated felonies). Others temporarily bar naturalization or raise good moral character concerns. Any criminal history should be discussed with an attorney before filing [§ 8 U.S.C. 1101(f)].

Where do I take the naturalization test in South Dakota?

Naturalization interviews and oath ceremonies are conducted at the USCIS Omaha Field Office (serves South Dakota).
