I'am a green card holder. I don't know what should be the correct answer for this question (form I-130. Question 14)
What date did you enter the U.S. with an immigrant visa or what date was your I-485 approved (this date should be on your green card)? What airport of border crossing did you use when you entered with an immigrant visa or what USCIS office approved your I-485? Your class of admission is listed on your green card.
