Naoki is right on many counts.
Speaking strictly about the US, CITES and phytosanitary paperwork is not optional, it is required in order to ship live plants internationally. You are also required to have a current and valid import permit from the USDA/APHIS in order to have live plants shipped directly from Brazil to the US.
The hobby import permit is free, but as was mentioned, the cost of CITES and phytosanitary paperwork can be costly, and that is not considering shipping and handling costs yet.
It is better to order from a Brazilian nursery that makes the international orchid show rounds.
And as was mentioned, I can confirm the fact that Floralia, (
Floralia Orchids), is one of those that does make the US show rounds.

If you're tired of growing Cattleyas, Laelias, or even Encyclias, maybe try a Maxillaria or an Oncidium. Perhaps a Sophronitis would be another appealing choice.
