B1 visitor for business may be admitted for not more than one year and may be granted extensions of temporary stay in increments of not more than six months each.
You may extend your stay in B1 status by a maximum of six months provided the b1 visa extension request is due to "an unexpected or compelling humanitarian reasons" such as medical treatment or unforeseen delay in conclusion of a business matter.
You must file the b1 visa extension request using Form I-539 and prove that you have adequate financial resources to continue staying in the U.S. and that you are maintaining residency abroad.
B.
Change of Status
You may change from a B1 visitor visa to another nonimmigrant category provided you can prove that you had no preconceived intent to change status. If you intend
to change status to F-1, M-1 or J-1, you must state your intent while applying for the B1 visa.
