Between now and whatever date they have targeted in April, be be aware the waiver process cases can still be working after that, and there is a tiny trickle of appointments right into May and early June. Each case is assessed on its own merits version vs. the waiver policy for the DQ. Some things are never waivered, some sometimes, some frequently, some almost always.
Not what you wanted to hear, but you can’t look at someone else’s experience and pin your hopes to that. You are being looked at as an individual. This time of year, in March or April, the medical officer who is the waiver action officer is inundated with case reviews. You don’t want him or her to rush these, right?
You are in a good position with an LOA.
As always, focus on what you can control, finish this academic year strongly, go PT, enjoy family and friends. If you get your wish, you only have 3.5 months left at home. After that, you’re a visitor and your life will have changed radically for the next minimum of 9 years. Live in the moment!
