I just got them, my DH was unemployed, although he just went back to work yesterday. The appt was very easy, you need a months worth of paystubs(or proof of unemployment in Dh's case). You also need to show your housing costs-house, utilities. They just tallied up our monthly totals and deducted part of our housing costs. Our card ended up with $137 for a family of 3. I currently am pg, so in Oct after our baby is born I need to reapply to get more benefits. I also have to call now that Dh is working, so I can send them a copy of Dh's paystub-we may make too much then and the lady who did my interview didn't want us to have to pay money back.
My nephew and his wife got the maximum allotment for their size family(3) last fall. My nephew was laid off and his wife had just had a baby, so she wasn't working. They got about $500 if I remember correctly, so obviously they had little to no income and weren't working. Not sure how that worked, but it did.
It starting to sound to me like WA is pretty easy to get FS, I had my interview and had my card within 10 minutes and it was charged and working the next day. Not sure if that could be because I already am in the system due to my pregnancy medical and DD's MCHIP. I used my card 2 days after I had my appt.
