Good morning sir , I have booked an US C1D visa appointment recently and already have appointment confirmation but I have 2 changes to do in my DS 160 form by which I made the appointment . Can I retrieve the old form and create another DS 160 form and go with both the old confirmation form by which I have booked and appointment and also the new corrected DS 160 form on the day of the Biometric and update the new confirmation form on that day ? Kindly advise on this .
