Sorry guys maybe I need to put like this.In this half and 1 year when I'm working in germany,I've been to US 9 times in B1/B2 visa due to official work.It used to be short trip like for 2,3 days and my lawyer has deducted those days too.In total it comes around like 30 days.My lawyer .is not worried on that.But I am now since I was in US on and off for 30 days altogether.So am I safe?
