H4 stamping without primary H1 holder (L to H conversion)

Hi, I was on L1 and moved to H1 since last Oct but do not have the H1 stamped in my passport

So as my dependents. Can my dependents travel to India and get their H4 stamping without me travelling?

My dependents have approved H4 petition but not visa on any of our passports. Please advise if there would be any issues with stamping?
