I have a plan to attend conference held in Greece April 2020. I have already purchased return air ticket. However, I have been informed by Greece embassy in Bangkok that obtaining visa for Greece needs to wait for a long queue (until the end of April. I didn't expect this to happen (my big mistake that I didn't check before purchasing air ticket). I have written email to the Greece embassy in Bangkok, but get no response.
My friend suggested me to go for Italy visa instead. Would it be possible to enter Greece with Italy Schengen visa?
