To import you need a permit which I recently applies for.
Last week I was informed that there was a moratorium on temporary imports by non residents. I could not get a straight answer on imports by residents.

I was speaking with Ms. Bautista. You may want to drop her a note.
If you are discovered bringing a a drone without a permit in they will impound it and return it when you leave the country. Or at least this is what they are saying.............
