Would they accept a VOE as a proof of income for help in rent assistance? Verification of employment.

Any type of mail with your address but they ONLY serve IRVING,TX

They should accept VOE. Realize Irving Cares only helps if you live in Irving. Also realize this sort of nonprofit often disburses FEMA funds (restrictions include FEMA will only help 1/year, proof to get help, expanse has to meet certain qualifications, et cetera). From what Miranda Lozano said, it sounds like she may have been rejected on those grounds. If they reject you make sure to ask what other bills might qualify. In fact I suggest bringing all your bills. That way if one of the others qualify you can produce records on the spot. If worse comes to worse ask for food. It is far easier to get food than it is to qualify for the likes of FEMA funds.
