My IFS date is March 2013 and UPT June 2013. Would it be more realistic to expect January or February for an EAD date/orders?
Yes it would. My dates last year were moved similarly to yours and ended up getting moved to February of this year. My IFS/UPT dates were Feb/April. Lots of studs got caught in the same situation... Find a job or start your masters.
Verizon has the best coverage on base. Haven't had any problems, I get 3 bars here in base housing and inside the squadron. I've heard AT&T is less than satisfactory and I can't say anything about the others.
