Yes it is!!! Trust me.....only travel after your son has gotten his GC! Those immigration ppl sitting at the airport are a bunch of dumb asses, who don't know jack about priority dates, immigration petition, visa number, etc. All they want to see is either a US citizenship or a GC. If you confuse them with complicated immigration terms, your son could be in trouble!

Ultron,
Do you think it is still risky (to travel)?
