For most steps, no. The greater part of the incorporation, tax and banking work can be done without you travelling, on a power of attorney issued at a consulate or executed abroad, apostilled under the Hague Convention and translated into Turkish. The Foreign Direct Investment Law (No. 4875) puts nothing in the way of a foreign investor incorporating remotely.
There is one practical caveat, and it is a banking one rather than a legal one: some banks want the authorised signatory to attend once in person, for the account opening or to verify the beneficial owner. That expectation varies from bank to bank. We coordinate the process remotely and prepare the apostille, translation and power-of-attorney chain in advance, so that if a trip is needed at all it is for the steps that genuinely require it — not for a queue that could have been handled on paper.
