How to Apply for Visa
US Department of State Information About US Visas
If you are traveling to the United States for tourism or business for 90 days or less with a passport issued by one of the following countries, you may be eligible to visit the US without a visa:
Andorra, Australia, Austria, Belgium, Brunei, Canada, Denmark, Finland, France, Germany, Iceland, Ireland, Italy, Japan, Liechtenstein, Luxembourg, Monaco, The Netherlands, New Zealand, Norway, Portugal, San Marino, Singapore, Slovenia, Spain, Sweden, Switzerland, United Kingdom
If you are traveling to the US with a passport issued by any other country, you must apply for a visa. Please read these procedures carefully:
1. To apply for a visa, you must have your own letter of invitation from COM.* conferences and summits. You must register for FULL CONFENRENCE PASS before you can request a letter of invitation. When you request the letter of invitation, please provide your detailed contact information, including your full name, mailing address, phone number, email address, company name, etc.
When you register for the conference from outside the United States, and your country DOES NOT participate in the Visa Waiver Program (see list above), COM.* will send you a letter of invitation with your registration materials.
Please contact us if you have questions about the visa-invitation procedure. See paragraphs 2 and 3 below for further instructions.
The conference committee provide two methods to deliver the invitation letter for international attendees. One is directly to email the signed PDF letter. The other is to mail the letter with original signature via FedEx. The 2nd method need the attendees to pay the delivery fees $100 for one address. If you need more than one FedEx to multiple addresses, please pay one by one for each. Please click here to make a payment via credit card. If you need bank transfer, please contact us soon.
2. After you receive the letter of invitation, call your local US Embassy or Consulate to arrange an interview. For information on the embassy or consulate closest to you, see Links to United States Embassies and Consulates Worldwide. Recommendation: visit the embassy or consulate a month before you begin the visa process, to obtain literature, forms, etc.
3. When you go to the embassy or consulate for your interview, you will be asked to pay a nonrefundable application fee and submit:
• Your letter of invitation to attend COM.*.
• A signed, completed application. The application form is available at all embassies and consulates for no charge.
• A passport valid for travel to the US at least six months beyond your intended stay in the US.
• Two photographs, 1.5 inches square (37 x 37 millimeters), showing your full face, without head covering, against a light background.
If you are denied a visitor visa, you may re-apply if there is new evidence to overcome the basis for the refusal. In the absence of new evidence, consular officers are not required to re-examine such cases.
Due to the fact that an application for a visa can be a lengthy process, COM.* recommends that you start your visa application process early prior to the conference.
