US Immigration from Ivory Coast

Hello VJ, I'm the petitioner for my wife and 2 stepsons, applied for as a family, and everyone received their visas this week.

Now, we're working on our travel plans to the US, and can't find a clear answer to this question - can mom and I travel to the US first, and the kids follow a few weeks later?

We're all together in now in one country, but the kids will go visit their dad & grandparents in second country once school lets out. Meanwhile they're on vacation, mom and I both finish our work and our home needs to be vacated. So, Mom and I would like to move to US while the kids are still on vacation, and the kids join us 2 weeks later directly from their vacation. (The alternative is that Mom and I find a place to squat and twiddle our thumbs waiting here for the boys to get back so we all can fly together)

So: Can the CR-2 visa holders enter together, as long as its AFTER the CR-1 has already entered?

Also, I don't think this will make any difference to the question, but just in case: we just celebrated our 2nd wedding anniversary, so the CR visas will be IR visas.
