A B-1 visa is a non-immigrant visa that allows foreign nationals to travel to the United States temporarily for business purposes. This includes attending conferences, business meetings, negotiating contracts, or exploring investment opportunities. B visas are typically valid for up to 10 years from the issue date, and travelers can stay up to 180 days per visit, with the option to return multiple times during the visa's validity.

As of December 2023, the average wait time (processing time) for most B1 visa interview appointments ranges from 2 months (Brazil) to over 2 years (Canada). To check the wait time for your specific embassy or consulate, enter your city in this handy State Department tool under the section “Appointment Wait Time.” Note that if you are applying for an interview in a country other than your home country, wait times may be longer.

The B1 is used for short business trips (conferences, meetings, contract negotiations, etc). Those with B1 visas cannot work in the U.S. in the traditional sense. As of March 2023, B1 or B2 visa holders can apply for jobs in the U.S. and attend interviews.
The B2 (tourist visa) is for tourism, vacation, or visiting friends and family. It also covers certain medical treatments and participation in social events or contests, like music or sports, without receiving pay. In most cases, a B1/B2 visa is issued together, allowing the holder to travel for both business and pleasure.

Depending on the context, the number of times you can visit the U.S. with a B visa varies. B1/B2 visas are multiple-entry, meaning they can be used to enter the U.S. more than once. There’s no set limit to the number of times you can visit the U.S. in a year, and it depends on the specific circumstances and discretion of the CBP officers who review your case each time you enter.
It’s important to remember that the B1/B2 visa is intended for temporary, occasional visits for business, tourism, or medical treatment. It’s not meant to be used for living long-term in the U.S. or spending the majority of your time in the country.
If officers think you’re trying to live in the U.S. through frequent or extended visits, or if you’re not maintaining significant ties to your home country, they may suspect you’re misusing the visa, which could lead to denial of entry or future visa issues.
While there’s no official limit, it’s vital to respect the purpose and restrictions of your visa to avoid any problems. If you need guidance on your specific situation, it’s a good idea to consult with an immigration expert.

Currently, the government filing fee for a B visa is $185, which does not include the cost of gathering documents and evidence and acquiring passport photos.

A B1 business visa is for many types of business activities in the U.S. If you want to apply for a B1 visa, you need to prove that your trip to the U.S. is only for a short time.
You must also show proof that you plan to return to your home country after your visit, and that you have a place to live outside the U.S. that you will not leave for good. These points help show that you will follow the rules of the B1 visa.

• Business Meetings: Attending meetings with business partners or clients.
• Conferences: Participating in business-related conferences or seminars.
• Negotiations: Engaging in contract negotiations or exploring investment opportunities.
• Training: Receiving short-term training from a U.S. parent company.
• Professional Services: Providing professional services as long as they do not involve remuneration from a U.S. source.
• Establishing Business: Exploring possibilities for setting up a business or investment in the U.S.

The B1 visa do not grant permanent resident status — it is a temporary visa, but you can adjust your status from a B1/B2 visa to another type of visa while you are in the U.S., as long as you meet certain requirements. This process involves submitting a change of status application to U.S. Citizenship and Immigration Services (USCIS).
