Question: how long after discharge can i use my gi bill?
Answer: You get 36 months of full-time GI Bill benefits and have no time limit on when you need to use them by. If you left the military before Jan. 1, 2013, your benefits expire 15 years from your discharge (if using the Post-9/11 GI Bill). If you are using the Montgomery GI Bill you have 10 years to use your benefits.
