I'm waiting to hear back from my permanent residency application, I've gone through 2 extension so far. The most recent one they sent me says I must provide proof that the permanent residency application was sent in order to receive any more extensions. Problem is, I don't have my receipt for when I sent it off. I've looked everywhere and I must have tossed it out not knowing. I do however have proof of funds (Receipt paid online, proof that I paid online, and proof that it was withdrawn from my credit card) Is this enough for proof? Or is there a way I can get something else?
