SPECIAL VISA TURKMENISTAN
If you apply in Turkmenistán.s Embassy in Tehran Vatanpour St, Farmanieh Avenue and Tajirish Sq, 22206731 phone, Open Sunday 9.30 until 11, and Every day (except Friday and Saturday) from 9 to 11, you have to wait about 10 days because they will send by fax to Asghabat. But you can go to Mashhad, and if the say yes in Ashhgabat, from Tehran they send the ok to Mashhad. So, in Mashhad you can go to Consulate Turkmenistan and fill the form, pay 55 USD and give them copy of your passport and of your Uzbekistan Visa. Then you get 5 days visas to cycle Turkmenistan. BUTTTTTTTTTTT, maybe when you arrive to Mashhad, Turkmenistan Consulte will be close for 4 days or 1 week without any information about when they will open. And maybe they tell you they don?t have any fax from Tehran. So, you have to smile and cry at the same time, speak some farsi, and Russian and maybe Turkish, and try , and try , and try. If they call to Tehran, and there isomeone in Turkmenistan Embassy in Tehran and the guy remembers you, maybe, you can get Turkmenistan visa in Mashhad in the same day.
Good luck and enjoy travelling through funny countries where no rules are the main Law.
