All visa applicants are advised to apply for their visa as soon as travel to the United States is contemplated, and not later than 3-4 months in advance.
Please confirm whether or not you need to apply for a visa. You may not need to apply for a new U.S. visa if you already hold a valid U.S. visa of the classification appropriate to your purpose of travel, or hold a passport eligible for travel under the Visa Waiver Program, or if you hold a Canadian passport.
Find out what visa type is appropriate for you
The type of visa you must obtain is defined by U.S. immigration law, and relates to the purpose of your travel. Please visit Visa Wizardto find out what visa type is appropriate for you. You can also visit Frequently Asked Questionsor find out about the Visa Waiver Program.
Please note that ICSSS Conference is not authorized to assist with the VISA process. The invitation letter from the organizing committees will be sent upon the request only when you register successfully, which may help but cannot guarantee you a visa.
Your name must be listed exactly as it appears on your passport. Any differences between the name on your passport and the name on your invitation letter or other documentation could lead to a delay and/or denial of your visa.
It takes time for the Embassy to process the VISA application, please register as early as you can to make sure you have enough time.
