Back in 2018 I applied for a tourist B2 visa to United States. I successfully obtained the document and subsequently travelled to US.
This year I am required to travel to US for business, and hence require a B1. I have filled out and submitted the DS-160 application (including the details of the previous visa number etc).
However, after doing so, I looked at my passport again, and as it turns out, the previously granted visa is in fact of type 'B1/B2'. It is valid for another 9 years, and for multiple entries.
I now realise my mistake; as it turns out I did not require any more documentation to travel. However, did submitting the additional DS-160 form have any effect on my status?
I know that one cannot delete a submitted DS-160, and I have not booked/attended an interview at an US embassy. Am I therefore safe to ignore the extra application? Would that information be available, or could it at all cause any problems, at the port of entry?
