H1B to H4 while h4 is still valid

I entered US on H4 and my H-1B was approved in October through a consultancy. But, I would like to visit my home town and come back to USA on H4 dependent as my employer has not been running my payroll and I have not been placed on a project. My previously stamped H4 is active until May 5th, 2017 . Would I need to go for Visa interview and get H4 stamped again? Will I face any issues regarding pay stubs?

Not required… you can enter into US using your H4, but keep in mind to carry copies of your spouse’s current H1 paperwork
