FOR EL SALVADOR AND GUATEMALA!
You MUST have a Passport for all international trips. You are responsible for all fees associated in getting a Passport. If you do not get your Passport by Spring Break and are unable to go, you will not receive a refund. Passports are around $100. Go to your local Post Office for an application. It can take up to 10 weeks for processing, so plan accordingly.
The Allendale Township offices are also a place where you can apply for a passport check out this link. http://www.allendale-twp.org/clerk/passport.html
The cost of the international trips do not include the additional Passport cost which is required for out of country travel. If you do not have a current passport, you should start that process now. More info including locations to apply can be found here. DO NOT leave this until the last minute. You WILL NOT be allowed to participate on this trip without a current passport.
