Hi everyone. So sorry to post what is probably the most stupid question ever but I honestly can't figure out which application form to use. I've checked FAQs and apologize if I've missed it. Need to apply for A & A for my parents. Dad is the vet and he needs household help. Mom is spouse and has severe dimentia. I have 21-526 and 21-534. Not sure if I can submit 1 form for both parents or if each parent needs separate app and if so, which one. Thanks for any advice. This is all so new to me.
