Visa Information

No visa is required for visitors to Mexico from Australia, Canada, New Zealand, the UK and the US, among other countries*. Visitors can stay legally for up to 180 days. At the entry point, you will be given a Mexico Visitor's Permit (FMM) to fill out. You will need to show it when leaving the country, to prove you are within the 180-day limit. If you lose the permit, you will need to apply for a replacement at the airport or a local immigration office (available in every city and many towns).

Tourist visas are not required unless an individual is staying more than 180 days.  Individuals requiring letters of invitation to obtain travel visas can contact Laura Spencer at lspencer@optica.org.  Please use the information below in your request. 

Important Information

• 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.
• If you are presenting a paper, include the title and session in which the paper will be presented.
• Please note that each individual requesting an invitation letter must fill out a separate form.
• All letters of invitation will be sent by a locked PDF unless otherwise requested. If you require a paper copy, please provide a courier account number or credit card number with expiration date with the original request.
• Optica reserves the right to request further information regarding the company or affiliation of the attendee to ensure the validity of requests. Meeting attendees do not need to wait until your paper is accepted to request a visa invitation letter.
• Optica is unable to contact embassies in support of an individual attempting to gain entry to attend a meeting.
• We recommend that you secure your travel visa before registering for the conference as cancellations after the preregistration cutoff may result in a cancellation fee.
