I wanted to go to Azerbaijan for a 3-day journey and I used Asan Visa web-based system. After 2 days they told me that my information was not match with my passport because one space character exists between two deferent parts of my family name and that space dose not exists in my passport. They forced me to pay another cost for a new request!! I believe it is rubbery to get addition money only for one space!! They can easily edit my family name and remove that space but they refuse my request!!
In Iran-Azerbaijan border also, that country officers were very rude. They requested addition money to do your process faster that other people who stood in line to enter that country!! I never go there for second time.
