Welcome from Dutchess County NY... I just received my full carry and took about 9 months from start to finish but this was a new permit and Dutchess is pretty gun friendly (as far as it can be in NY...lol). If you have a permit already it should be a no Brainer... Just check the rules of your county and have everything in place before your court date... Which will be probably 6 months from when you request it.
If you haven't taken the NRA Pistol Course since you have had your permit I would do that as well as everyone I know in NY that has requested an upgrade needed to take it again... So if you do it all ahead of time you will save the wait.... Where in NY?
