The B-1 visa is issued to individuals traveling to the United States for short-term business and short-term unpaid training; the B-2 visa is issued to tourists visiting the United States for short-term sightseeing and visiting purposes. "B-1" Visa: The B-1 visa is applicable for short-term business travel. This includes contract negotiations, attending exhibitions and conferences, short-term training, and discussions with suppliers and clients. Short-term training of less than 90 days can also utilize the B-1 visa.
The B-1 visa is not applicable for working in the United States. "B-2" Visa: The B-2 visa is applicable for tourism purposes, such as sightseeing, visiting friends and relatives, and receiving medical treatment. Work is not permitted during the stay in the United States. The Department of Homeland Security generally allows parents to stay in the U.S. on a B1/B2 visa for six months, but please note that any extensions will reduce your chances of obtaining a visa in the future. When the stay in the U.S. lasts for up to one year or longer, we will question your claim of not intending to abandon your residence abroad.
Applicants must meet the following conditions:
1. You must have a residence outside the United States that you will not abandon;
2. You are only making a limited short-term stay in the United States; you will leave the United States after your stay ends;
3. And you have sufficient funds to cover the expenses of this trip.
It is important for applicants to note: Under Section 214(b) of the Immigration and Nationality Act as amended in 1952, every visa applicant is legally presumed to have immigrant intent. Unless the applicant presents evidence to convince the interviewing visa officer that this presumption can be overcome, the applicant cannot obtain a visa.
