After receiving my H4 visa .i am planning to go USA after 1 yr time after my husband settle down properly

My question is it is compulsory for me and my son to travel with my husband who is in H1b visa

You can travel even after 1 year but within the validity of visa .

It is not compulsory for you to accompany yr husband
