Unfortunately I am still missing the required letters of intent. I did not think to do that (or the passport photos) on the last visit. I have read on this site that a wet signature is better so I was going to get all those things on this upcoming visit. I wish I had the forethought to get everything then as if I had we would be a year into the process! Hindsight is 20/20.
I did mention the benefits of the CR-1 vs. the K1 to her but she said that she did not want to start a marriage with being separated to which I agree. I really do envy the people who are able to do the marriage visa and wait out the process with their spouse in the foreign country. On the bright side it just gives me more time to save enough to eat the increased cost of the AOS.
Thank you for your input. I didn't think Lima was an overly tough consulate either especially if the USC attends the interview but I wanted confirmation. I will follow your advice and front load anyway just to be safe. In regards to the calling each other husband/wife, I made sure to let her know to not use that word because I have read stories on this forum where, even if said casually, it could be a death sentence for this petition.
