After returning home, you can apply for a B-1/B-2 visitor visa for business meetings and short stays. You must clearly show strong ties to Brazil, including your business, residence, and ongoing activities. This option allows flexible travel but does not permit work in the U.S.

If your business has a U.S. component, the E-2 Treaty Investor visa may be an option. Brazil is an E-2 treaty country, making you eligible if you invest substantially in a U.S. business. This visa allows repeated entry and longer stays. It requires active business involvement, not passive travel.

You may also consider applying for a new nonimmigrant visa in the future, such as an H-1B or O-1, if your qualifications and opportunities align. Maintaining a clean immigration history now will make future U.S. travel much easier.
