If you apply for a B-1/B-2 visa, you must demonstrate to a consular officer that you qualify for a U.S. visa in accordance with the U.S. Immigration and Nationality Act (INA). Section 214(b) of the INA presumes that every B-1/B-2 applicant is an intending immigrant. You must overcome this legal presumption by showing:
That the purpose of your trip to the U.S. is for a temporary visit, such as business, pleasure, or medical treatment.
That you plan to remain in the U.S. for a specific, limited period of time
Evidence of funds to cover your expenses while in the United States.
That you have a residence outside the U.S., as well as other binding social or economic ties, that will ensure your return abroad at the end of your visit.
