As the visa application process is significantly different for entry into the United States than the process in many other countries, ANSI has prepared the following information so that delegates understand the steps they need to take.
We urge you to carefully review all the information on procedures for nonimmigrant visa application provided by the U.S. State Department.
The following online location provides an official source of information about U.S. visa policy and procedures: http://travel.state.gov/visa/visa_1750.html
Please follow all instructions provided on the website for your local U.S. Embassy or Consulate General website to avoid costly delays.
U.S. visa policy permits citizens of certain countries to travel to the U.S. without a visa. For information about whether you may require a visa, please find such information at the following location online:
Your application must be submitted through the U.S. Embassy or Consulate General that has jurisdiction over your place of residence. The following is a link to the list of all U.S. Embassies and Consulates worldwide: http://www.usembassy.gov/
Due to potentially long wait times for a visa interview and possible requirements for additional processing, applicants are encouraged to submit their visa applications as early as possible – no less than 30 days and ideally at least 90 days in advance of the intended travel. Wait times for a visa interview can range from a few days to several months, depending on location and time of year.
Applicants who are engaged in certain sensitive scientific or technical fields may be subject to additional administrative processing procedures, which can add additional time to the visa application procedures, in some cases up to 120 days.
Applicants for U.S. visas should come to the visa interview with a thorough understanding of their travel plans and logistics. They should bring their invitation letter, copies of meeting agendas, travel itineraries and other documents on official letterhead, as well as documentation to help demonstrate “strong ties” to their home country. For information on what constitutes “strong ties,” visit: http://travel.state.gov/visa/frvi/denials/denials_1361.html

Should you encounter any problems in the visa application process, please contact the issuer of your invitation letter as soon as possible. While ANSI has no authority to influence consular decisions, it may be possible to provide guidance on additional steps that could be taken, or otherwise be of assistance.
