I am an Australian citizen. Originally I intended to stay in Canada for a working holiday. I am supposed to apply for B-1/B-2 including transiting. However, my plan has changed. I don't need a B-1/B-2 visa anymore. I submitted DS-160 form, paid the fee.
Now may I just simply cancel my visa interview next week?
I applied ESTA and got approved until mid 2018. One of the ESTA questions says:
Have you ever been denied a U.S. visa or entry into the U.S. or had a U.S. visa canceled?
As long as my visa has never been denied or cancelled (I never even applied for a single visa), I should say "no"...right?
Can I still enter the US in the future with my current valid approved ESTA?
