Visa for Costa Rica
I would double check but about 6 months ago the requierements were as follows
(a) Completed application form.
(b) 2 passport-size photos.
(c) Passport valid for 6 months at time of entry.
(d) Proof of sufficient funds to cover duration of stay.
(e) Return or onward ticket.
(f) Letter from Job saying how long they have been employed and whats their salary
I believe its quite simple to get thiss visa way easier than US,European or Canadian Visa
The Visa cost was 20 usd
Best of luck
