Very grateful to @Shaksaat for previous help on my port of entry questions. I have another and hoped someone might help...
I'm the spouse of the green card applicant and we've had our (successful) embassy interview and are awaiting collection of passports. For practical reasons he's hoping to enter the US first, present himself with package etc and get his I551; and then for me to follow say a week or a month later - and get my stamp (I won't have a 'package' and it may all be online anyway). I'm wondering if there are any disadvantages in this plan. I know I won't get my green card stamp until I do but I'd be keen to know whether there are any other potential problems/ pitfalls in not going together.
