How can I go about applying for the active duty Green to Gold program (Master’s degree) when slated for an assignment to Korea?

Very hard to delete your assignamet. Here is the thing (short version): 1) as you mention you need to get a hold with a ROTC program and discusse your interest on the green to gold program; 2) if given a thumbs up then you need to apply for college and get accepted in the program; 3) be endorsed by your chain of command; 4) process your application thru Cadet Command; 5) and wait for your orders.

By the time it all happens you might be over halfway of your Korea tour.

You will pcs to Korea and if you get accepted they will pcs you again to the school location where you get accepted. I just pcsed to ft. Eustis in January and got accepted this year and I am pcsing back to Colorado 6 months later. Go ahead and just move forward with your packet it will all work itself out, do not let anyone try to tell you otherwise.
