I have an upcoming travel for a conference in country A. But their consulate is pretty busy and I would like to get my visa sooner.
Can I go to the consulate of a different country B which doesn't need appointment for visa applications and get my visa from there? I can schedule to be in A for 5 days and in B for 7 days.
What if I change my plans later not to visit country B at all and go a country C or just stay in A the whole time? Will there be issues when entering or exiting Schengen states?
