I-140, I-485 filing and spouse and child abroad

[okct]

My Perm Labor certification was approved much faster than I expected. My wife and son are abroad at this time for summer vacation. I needed to file I-140 and I-485.

May I file mine now and send theirs once they arrive or what would I do? They will be back in 2.5 months. The travel ticket is scheduled that way. I am not from India and priority date is current. Please suggest me.
