I have an I-797 valid until next year, but my H1B visa will be expiring next month. I am travelling to India and completing a DS-160 for this.
Six years ago, my B1 visa application was refused. The officer didn't give me any documents; he just told me to try again and returned my passport.
On the DS 160 application, what i should answer to the question whether I have ever been refused a US visa? I didn't get any notice such as a 214B or 221G.
Should I say yes to the question, but that I don't know the reason for the refusal? I am confused to whether I should select yes or no.
