Hi Robert, It depends on what type of involvement you have with the New GI Bill as to whether there may be any additional service obligation. If you have earned the New GI Bill benefits with your military service and you are planning on using the benefits yourself, then there is no additional service obligation.
However, if you are planning to transfer your New GI Bill benefits to an eligible spouse or dependent child, then there probably will be an additional service obligation before the transfer is approved. If you are planning to use transferred New GI Bill benefits that a service member earned, than that service member will probably have an additional service obligation.
The amount of benefits you have is based on the amount of time you have been on active duty after 10 September 2001. If you have been on active duty for at least 90 days then you are eligible for 40 percent of the New GI Bill benefits, and it continues upwards with additional time on active duty until you become eligible for full New GI Bill benefits with 36 months of active duty time.
