I obviously wasn’t being clear. There is no such thing in the mind of USCIS or CBP as activation, a grace period, a settling trip, or anything else with those kind of meanings that people in this forum like to use. It is the absences that count. That’s it. If you have been out for a while (usually but not always defined as longer than 6 months), they will be likely to ask you about the reasons for that absence. So no, they wouldn’t regard that as a “settling trip” - or any other trip as such in fact, because that isn’t a thing to them, it’s just a thing to you. They may question you at any stage, and different CBP officers may decide whether different lengths of time warrant questions or not. The officer may well question you on something like a biometrics trip just because you’d probably only have it booked for a week or something.Yes, I have read that. Been told countless times that the first 12 months they are most lenient if you’re outside the US for the maximum time. For subsequent years, it’s best to do under 6 months absence. If you have multiple trips back and forth to your home county, it can look like you’re using the green card as a travel visa rather than permanent residency. My concern is whether a 2nd trip into the US post activation to do biometrics would be regarded as the “settling” trip. And then when I enter a 3rd time later in the 12 month period, the border control officer may question me.
