Hi, writing to you as i need help 

There are couple of queries for DS160 form and submission

I have a B1/B2 visa and had applied for the same in April 2019 from my company, so the old account exists and i may have to continue with the same. After i login i can update my profile so i will update my personal email - earlier it was company email id.  I’m assuming that the old email address is just a username at this point and doesn’t have any relevance. Correct?
But i see the DS160 form as the older one, Now if i fill the new form will it automatically take the new form number or i may have to enter the same manually ? will it be okay  ?

We just don’t want to submit the application and have the old number mess anything up. Please advise on this. If this is confusing.

And what did you select for PERSON /ENTITY paying for your trip ? 

Should I mention my current organisation details , as i am on notice period in my firm and will be not working at the time of interview?
