This is what my doctor said, with respect to the complications I am having in my country getting clearance for this certification:
I have discouraging news from the DEA. The man who called back Bill? Parks? said that they only issue Certificates of Authorization to medical mission groups that are bringing in benzodiazepines (or other controlled substances) to distribute to poor people in the Philippines. They do not issue certificates for individual use. His reading of the Philippine law is that if you are only taking in 30 days, you are okay with a note and a prescription, but for two months worth this probably won’t work. He was not hopeful but thought that either the embassy or the customs and border control people might know if there are any other options for you to obtain a certificate of authorization.
