Generally, a citizen of a foreign country who
wishes to enter the United States must first obtain a visa,
either a nonimmigrant visa for temporary stay, or an immigrant
visa for permanent residence. Visitor visas are nonimmigrant
visas for persons who want to enter the United States
temporarily for business (visa category B-1), tourism, pleasure
or visiting (visa category B-2), or a combination of both
purposes (B-1/B-2). If you hold a Canadian
passport, please visit the following website at

If you do need to apply for a nonimmigrant visa, please follow
the steps below.
Note: If you are under 14 or
aged 80 or over, or if you previously received a U.S. visa that
expired within the last 12 months and you are returning to the
United States for the same purpose of travel, you may be able to
obtain a visa without coming to the consulate for an interview

For most attendees, it is easier to
apply for a Tourist ("L") visa; an invitation letter is NOT
required for obtaining a Tourist visa.
If some participants need another type of visa that does require
an invitation letter, the ICBDE 2018 conference committee will
be glad to help. To obtain an invitation letter, please send

author, your accepted paper ID. The Conference Secretariat will
