During a US visa interview in 2026, the most critical thing to avoid is any statement that suggests you have "immigrant intent" if you are applying for a non-immigrant visa (like a B1/B2 tourist or F-1 student visa). Do not say things like "I plan to look for a job while I'm there," "I might stay longer if I like it," or "I want to join a protest or political campaign." These statements signal to the consular officer that you may not return to your home country, which is a primary reason for visa denial under Section 214(b). Additionally, never lie or provide inconsistent information; do not say you have never been denied a visa if you have, as the officer already has your full record on their screen. Avoid giving overly long, "rehearsed" stories or irrelevant details that make you sound defensive. Finally, refrain from being rude, arguing with the officer, or saying "I don't know where I'm staying" or "I don't have a return plan." The goal is to be concise, honest, and demonstrate strong "ties to your home country" through your employment, family, or property.
