Traveling to the United States requires most international visitors to obtain a US visa. From applying online to scheduling interviews, paying the correct fees, and choosing the right visa type, the process can feel overwhelming.
This guide breaks down the US visa application process step by step and explains the main visa categories, including the US tourist visa, US student visa, and other US travel visa options.
What is a US Visa?
A US visa is an official document that allows foreign nationals to travel to the United States for a specific purpose—whether it’s tourism, study, work, or permanent residency. It is usually stamped or affixed to your passport and presented at a U.S. port of entry, where Customs and Border Protection officers decide whether you can enter.
Types of US Visas
| Visa Type | Category | Purpose |
|---|---|---|
US Tourist Visa (B-2) | Short-term visit | Vacations, sightseeing, visiting family/friends, medical treatment, social events, short non-credit courses |
US Student Visa (F-1) | Academic studies | For international students attending universities, colleges, or language schools |
US Student Visa (M-1) | Vocational/non-academic | For vocational training or non-academic programs |
US Travel Visa (B-1) | Business | For meetings, conferences, negotiations, or business-related activities |
Work Visas (H-1B, L-1, O-1, etc.) | Employment | For temporary work assignments in the U.S. |
Immigrant Visas | Permanent residence | For those applying to live permanently in the U.S. (green card) |

US Visa vs ESTA
If you are a citizen of a Visa Waiver Program (VWP) country such as Singapore, you may not need a traditional U.S. visa for short stays (up to 90 days). Instead, you can apply for ESTA (Electronic System for Travel Authorization) online. However, ESTA is only valid for tourism, business, or transit—not for work or study.
