For sure. This is the email address:
Infomiami@mirex.gob.do
If I remember correctly, I just found that on the site. Once I received a response it was easier as I was communicating with a specific person and not a general informational email address. I agree, it's incredible that they operate that way. Once you're there though, it's efficient, friendly, etc. It's just getting in there initially but again, if all else fails, I would just show up if you can. I did ask on the first visit HOW to make an appointment online and was told that "the appointment button was removed as it was not working correctly". Again, you have to scratch your head and wonder how on earth, in this day and age, can't these things be sorted out.
