I belong to Pakistan and doing PhD in Italy. My research paper is accepted for conference in US. I want to participate in conference but facing confusion about the visa type.
What type of visa is required to attend a conference in USA, B1 or J1?
Attending an academic conference counts as a "business" purpose, so you need a B-1 visa.
J-1 is for formalized study or exchange programs of longer duration than the handful of days a conference will last.
