Paradise operates on FAA certificates, not sure how that works. So perhaps the immigration problem is not that big of a deal.
Don't matter the same with LACSA and TACA, they have both FAA certificates, LACSA A320 are all November, and register in the USA.
You still need to live in Costa Rica. Then you will be required CR passport. Anyhow I am in Miami asap I will get you the info!!
