Purpose: The B1 visa is for individuals traveling to the U.S. for business purposes, such as attending conferences, meetings, negotiating contracts, or consulting with business associates. The B2 visa is for tourism, vacations, medical treatment, visiting family and friends, or any other activity that is recreational or social in nature.

Duration: The B1/B2 visa is typically issued for a period ranging from 1 to 10 years. However, the actual length of stay allowed in the U.S. during each visit is determined by the U.S. Customs and Border Protection (CBP) officer at the port of entry. They will stamp the I-94 arrival/departure record with the permitted duration of stay, which is usually up to 6 months.

Application Process: To apply for a B1/B2 visa, you must complete the DS-160 online application form and pay the required visa fee. You will also need to schedule an appointment for an interview at a U.S. embassy or consulate in your home country.

Interview: During the visa interview, you will be asked about the purpose of your visit, your ties to your home country, your travel itinerary, and other relevant information. The consular officer will use this information to determine if you qualify for the visa.

Ties to Home Country: To be approved for a B1/B2 visa, you need to demonstrate strong ties to your home country, such as a stable job, family, or property ownership, which will give the officer confidence that you will return after your visit to the U.S.

Validity and Multiple Entries: The B1/B2 visa may allow for multiple entries, depending on the discretion of the U.S. consulate. However, each entry is usually limited to the duration of stay specified on the I-94.
