After some research , i found out that to get my visa , i have to buy a whole package , the following is what i received from a travel agency
According to our tourism regulation you should book hotel and guide during your stay in Turkmenistan.
So your quotes here below.
1- 100$ LOL
2- cheap hotel 30$×7days= 210$
3.-tour guide 45$×7 days= 315$.
These are your minimum tour package you should pay.
I am wondering if i can just go with the invitation letter ? or is there any cheaper option to pay for the visa upon arrival ?
