The USA announced earlier today that it would resume issuing visas for Turkish citizens seeking to enter the USA. Turkey has reciprocated by removing the ban on travel to Turkey by US Citizens.
The lifting of the bans are effective as of today.
The bans were first put in place on October 9 as part of the American protest over the arrest of a Turkish citizen who worked for the US Embassy in Ankara. The Turks claim the employee has links to Fethullah Gulen, an individual that Turkey believes is behind terrorist attacks within their borders.
With the removal of the travel ban to Turkey, US can now once again purchase visas to enter turkey in Istanbul at a kiosk located near passport control. The current cost of the visa is $30.
