What is the term for your husband or wife?

The term "spouse" specifically refers to a husband or wife in the context of a legal marriage. When discussing the N-400 application and related immigration processes, using the correct legal terminology is crucial, as it aligns with the definitions and relationships recognized under U.S. law.

While "partner," "significant other," and "companion" can describe romantic relationships, they do not necessarily indicate a legally recognized marital relationship. For immigration purposes, "spouse" is the appropriate and legally binding term to use, as it clearly denotes the formal commitment between two individuals recognized by law, which is essential for various rights and obligations under the immigration system.
