A related question to this great discussion: We arrived in the US September 3, 2021, and we and our children received Social Security cards and Employment Authorization Documents. We could make a first-year choice for 2021 in May 2022 (the 183 days between 2022 and 1/3 of 2021). But would that qualify for the child tax credit and enhanced benefits for 2021, or only if we had been here more than 6 months in 2021? Thanks for any advice.
