B1 Visas are issued to individuals granted entry into the US for very limited times to conduct their own business. An individual can do his/her own research and can receive some reimbursements or honoraria, but these situations are extremely limited. Regulations governing B-1s are found in the Foreign Affairs Manual 9FAM 41.31
