Dependent is a full-time student so I check "code S" (for EIC), if I check "YES" for the 6-month box, dependent shows up on schedule EIC.  But one of the parent with whole year permanent resident card did not live more than 6 months in 2024 in the US. Should I check "NO" for the 6-month box ? If I do, dependent will not show up on schedule EIC.
