Hi,

I am an Australian PT going through the long wait for FCCPT to get back to me (am on week 27 and no reply as of yet) and planning on going over on an E3 as well. I did the Type 1 review due requiring the health worker certificate. You may not need it for Colorado (?).

Have found the following Facebook page with some current updates on waiting times and other useful information.
The group is called "FCCPT Rule Changes and Updates"
FCCPT Rule Changes and Updates Public Group | Facebook

Hope it helps.
