You may need a U.S. tourism or business visa (B-1/B-2) if you are a citizen of a country that is not part of the Visa Waiver Program (VWP) and you plan to enter the United States for tourism or business for stays of 90 days or less. This type of visa is typically issued for the purpose of visiting family, sightseeing, attending a conference or business meetings, or other similar activities.

It’s important to note that even if you are a citizen of a VWP country, if you plan to stay in the U.S for more than 90 days, you will still need a B-1/B-2 visa regardless of the purpose of your trip.

It’s also worth noting that even if you are not planning to immigrate to the US, but if you have certain issues such as past visa denials, criminal records or other inadmissible factors, or if you are working in the US or are being paid by a US company or organization, you will still need a B-1/B-2 visa regardless of the VWP status of your country.

In order to apply for a U.S. B-1/B-2 visa, you will need to submit an application, pay a fee, and attend an in-person interview at a U.S. embassy or consulate. The process usually takes several weeks, and the visa issued will be valid for a certain period of time, usually 10 years and it allows multiple entries during that period.
