How to Verify a GCA Conference Invitation Letter
To verify a GCA conference invitation letter, go to verification.globalconference.ca and enter the Registration Number and Passport Number printed on the letter. A successful match confirms the registration is genuine.
Does GCA Guarantee Visa Approval?
No. Global Conference Alliance does not guarantee visa approval. An official GCA invitation letter is supporting documentation for your application, but Immigration, Refugees and Citizenship Canada (IRCC) or the relevant U.S. consulate makes the final decision. GCA cannot influence or appeal visa outcomes.
How Do I Know if a Conference Invitation Letter Is Fake?
A conference invitation letter is likely fake if you did not complete paid registration with the organizer, if the sender pressures you for fees outside official channels, or if the letter cannot be verified. For GCA, always confirm Registration Number and Passport Number at verification.globalconference.ca before trusting a letter or using it for a visa.
Listener vs Author vs Speaker Registration
Listener registration is for attending sessions without presenting. Author registration is for participants who submit a paper for presentation and publication opportunities. Speaker registration is for invited or selected speakers presenting without a formal paper publication track. Ticket prices and inclusions vary by conference; check the specific event registration page for exact fees.
