The site, travel.state.gov, contains information regarding obtaining a visa for those traveling to the United States. The embassy and consulate websites have very helpful advices about procedures, timelines, communities served, required documentation, and fees. An invitation visa letter will be provided, and generated by the EDAS system, if the paper is accepted.
If you are booking your stay at the Colonade hotel, you may wish to mention your attendance at the Northeastern workshop (code NEU) when making reservation via phone/email. Subject to availability, the hotel will provide you with a discount.
