H4 EAD renewal

[Anjel]

Hi

My spouse employer filed two different  797 for him. One was a PP filed in june and got approved in 15days valid till Aug 2017 and other one was a normal processing which was filled in april and got approved in Jan 2017 valid till april 2019.

I filed my h4 ead in dec from Opt to h4 and Ead concurrent filling on the basis of PP 797. So my h4 ead was approved till aug 2017.

now i want to renew it on the basis of other 797, do I have to file for h4 status again or should i just file form 765 for EAD.

Thanks
