usa – I have a valid Esta Visa and i got Refused with B1/B2 US Visa

Why on Earth did you apply for a B1/B2 visa? Unless you’re staying for over 3 months, there was NO reason to do that.

No, you’ve now messed up your immigration record and cannot use ESTA ever again. You’ll have to get visas for the rest of your life, though on the bright side of things they’re usually valid for unlimited entries within 10 years (with a 6-month duration of stay each time – can be extended)
