Application withdraw after getting 221 g

Hi Saurabh,

I appeared for H1B Visa Interview in Oct 2017.There I received 221g and they took the original 797 and asked for the client letter.

My petitioner suggested me to withdraw the VISA application as the end client change and the previous client letter could not be managed.

I have couple of questions here,

Is it safe to withdraw the application?

And if I withdraw the application now, what will be the process to reinitiate the stamping and how could I get back the 797?
