H1B Dropbox eligible but still got Visa appointment

[vinays4ad]

Hi All,

I have been working in US from past 2 years,

1st year I was working for Company A as consultant in a client location. My H1 Visa from company A is still valid till Sep 2018 

After one year I shifted to Company B & started working as Full time Employee for a reputed firm in USA. I have got my approved I797A copy from company B after my H1 Transfer, which is approved till Sep 2020. 

Now I need to go to India for 2 week visit in July. Due to my H1 transfer, I need to get it stamped before I return to US. For which I filled up my DS160, and when taking appointment it did not prompt me for any DropBox, but asked me to schedule appointment at consulate 

As my initial H1 is also valid till Sep 2018. I should be eligible for dropbox, But not sure why I was asked for VISA interview at consulate. Could somebody explain after H1 transfer to different company  Do we need to go for in-person Stamping, since my initial H1 with previous employer is also Valid till sep 2018. Have the Policies changed ?

I did take appointment at Chennai. But was wondering if I did any mistake in filling up DS160. since I have only confirmation page of my DS160 & did not save a copy of DS160 while filling. I cannot review the same now.

Also Can I fill up new DS160 again & take a fresh appointment now. Please Suggest.

Thanks.
