Change US Embassy After Filling DS 160 (for Visa Stamping?)
You can change US embassy interview location after filling DS-160 within the same country. No need to fill new DS160 form. Move H1B interview from Delhi to Mumbai.
Can I book US Visa interview in different US embassy?
You can change the US embassy or choose a different city for your US visa interview after filling DS-160 without changing or filing a new DS160 visa application form.
The new US consulate that you choose should be within the same country.
Example:
If you have filed your H1B visa interview application at the Delhi US consulate, and now want to change it to Mumbai as there are earlier interview dates available in Mumbai, you can do it.
Similarly, you are allowed to change the embassy location in Mexico for US visa stamping.
No need to fill new DS 160
There is no need to fill another DS 160 if you want to change your US embassy location.
The new US embassy that you choose for a visa interview appointment will be able to access your DS 160 based on the unique DS 160 confirmation number.
