U.S. citizenship requires the naturalization process, which typically takes several years and involves meeting requirements such as residency, good moral character, and knowledge of English and U.S. civics.
If the person marries a U.S. citizen, they may be eligible to apply for permanent residency (a green card) through their spouse. Once permanent residency is obtained, they can apply for naturalization after meeting eligibility requirements.
Regarding travel to Brazil: the student visa may allow travel outside the U.S. and return if the visa status is maintained and terms are followed. However, check with USCIS and the Brazilian consulate or embassy for the most current guidance on travel while on a student visa.
