3 visits in total, 2 while being in a relationship. First visit was two weeks, second visit was 6 months, and the third visit was 2 months (this year). Not any red flags that I can think of - we are only one year apart in age, both speak Spanish, she has never visited the US. She does have an instance where Mexico turned her back to Ecuador during a planned vacation we had in 2020 because they believed that she was going to cross the border with me, despite hotel and resort reservations bought and paid for. Interview is still TBD - we are in NOA1 now nearing its one year anniversary.
