Visa Information Visa Information to Attend AACE Conferences The following information may be helpful when applying for a Visa to enter the U.S. to participate in an AACE/SITE conference. Please note that instructions and policy may change, so refer to the government websites below. Easy to follow instructions on applying for a U.S. Visa Request a Conference Letter of Invitation To help you substantiate why you are attending the conference, AACE/SITE enables authors, who have submitted a conference presentation proposal or who have paid the registration fee, to print a personalized invitation letter: here If you have NOT submitted a proposal to the conference and are requesting an invitation letter, please send your justification to this address. Apply as early as possible We recommend applying at least 4 months in advance. Some consulates may have backlogs in scheduling visa interviews, so applicants should first contact the consulate to find out how long the wait is for an interview. Estimated wait times for your consulate may be available here. Check the Visa Waiver Program (VWP) to see if your country is listed — Some non US participants may not need visas if they are citizens of countries on the Visa Waiver Program (VWP). However, all citizens of VWP countries must have a Machine-Readable Passport (MRP) in order to travel to the United States without a visa. An MRP is needed to apply for a visa. Information on the Visa Waiver Program and list of countries is available here. Check your visa expiration date If you have a U.S. visa, check the expiration date to make sure that the visa will not expire before your planned travel date. What you need to apply Information about visitor visas and what a person needs to apply, is available on the U.S. Dept. of State’s Visa Services web site. To apply for a visa After identifying that a visa is needed, non U.S. travelers should contact the Embassy Consular Section in their country to determine visa processing timeframes. We recommend contacting the Consular Section. Look for posted timeframes on the internet or call the Consular Section to hear recorded information about visa processing timeframes.
