If you require an invitation letter, please email visa@icps2014.org. Please provide your full name, mailing address, passport number, date of birth, passport validity duration, country of citizenship, telephone number, and mobile number (include country code for both phone numbers).

Attend Your Visa Interview

During your visa interview, a consular officer will determine whether you are qualified to receive a visa, and if so, which visa category is appropriate based on your purpose of travel. You will need to establish that you meet the requirements under U.S. law to receive the category of visa for which you are applying.

Ink-free, digital fingerprint scans will be taken as part of your application process. They are usually taken during your interview, but this varies based on location.

After your visa interview, your application may require further administrative processing. You will be informed by the consular officer if further processing is necessary for your application. If further administrative processing is required, it will be additional time after the visa applicant’s interview by a Consular Officer. Applicants are advised of this requirement when they apply. Most administrative processing is resolved within 60 days of the visa interview. When administrative processing is required, the timing will vary based on individual circumstances of each case. Visa applicants are reminded to apply early for their visa, well in advance of the anticipated travel date.

Important Notice: Before making inquiries about status of administrative processing, applicants or their representatives will need to wait at least 60 days from the date of interview or submission of supplemental documents, whichever is later.

When the visa is approved, you may pay a visa issuance fee if applicable to your nationality, and will be informed how your passport with visa will be returned to you. Review the visa processing time, to learn how soon your passport with visa will generally be ready for pick-up or delivery by the courier.
