Question – After returning to the US after a sabbatical abroad month

After returning to the US after a sabbatical abroad ( 11 month) the immigration officer said a rentry form should have been filled prior departure, due to >6 month outside USA. He subsequently “flagged” me, resp my green card. What does this mean? I dont plan to be outside the US for more than 2-3 weeks at max in the next 1-2 years. Thank you

Question – I am a US citizen and I am applying for

I am a US citizen and I am applying for a GC for my dad. His wife of 21 years is not my mother, and they were married after my 18th birthday. Will his wife be included in his GC application? How can we get his wife to migrate to the US with him?
