should use dual-status residency alien or resident alien tax filling choice ?

Hi experts, 

 

 I and family (spouse and child) just move in the U.S at the end of Dec-2024. We had GC on that day.

During tax year 2024, I and spouse just have income from outside U.S (not from U.S companies and source of U.S) plus a portion of K-1.

My concerns are: 

 1. Should I and my spouse be treated as residency alien for the full tax year 2024 ? If YES, what's kind of income sources have to be filed? just K-1 or everything world wide ?

 2. If filing as dual-status, what's kind of income sources have to be filed in which forms? 

 3. How can I file tax credit for amount tax paid from foreign income? during the time of nonresident of the year 2024

 

Thank a lot for your advises
