I have a scenario, I applied for my parents in 2021, I attached 3 NOAs for 2018, 2019 and 2020. In 2023 Immigration informed me that my MNI for 2018 did not meet and because the process took them longer than 12 months, I can submit my latest 3 years of NOA from CRA to the immigration which I did. My LICO for 2019 to 2023 does meet the requirement. Today I received a letter that sponsor is not eligible to sponsor become of MNI not met. What happened here, they asked to submit more documents? I did submit my latest CRA documents starting from 2020 to 2023 already. Any suggestion?
