My passport will be 5 months and 29 days from expiration when I enter Costa Rica for three days. I have proof of onward travel and am expecting my new passport back in the mail while I am away. Any idea how this may play out? I would hope the agents would see this for what it is...constant travel makes applying for a new passport difficult, and this is as close as I have ever come to not having one. Fingers crossed they will just point it out and not ban me from entering!
