I'd say MImi has 10 times the credibility you do, but you have zero credibility and 0 x 10 = zero. So she has lots of credibility, and you have none.
This is the USCIS link. It does not look like you can do it in under 5 years unless you were a permanent (immigration resident) first. I strongly suspect that you and the dog and Mimi may be talking about different aspects of the process.
