The OP wants to go through immigration with family, so pre-cleared flights would not work. Those might arrive in the same concourse of International, but the OP would be upstairs at the departure gates level while family is downstairs going through immigration.

So, this would require the OP to arrive in the same concourse (A) on an international flight around the same time as family members, and not on a pre-cleared flight. It’d be hard to get the timing of all that right. I wouldn’t recommend trying.
