How many years I can stay in USA without GC for the below case?

Please help me to clarify the below.


My current H1 visa is valid until September 2015. I want to know how many years I can continuously stay in USA without filing the GC and applying only with extensions.


I have made the below US travels and I'm in an assumption that my 6 years clock got reset between trip 3 & trip 4. I'm assuming I can stay around 3 and half years, but some of my co-workers telling clock reset may not apply if you are on the same petition even though we have 1 year gap. Please clarify me on this.


trip1. 3 months 17-Feb-07 15-May-07 B1

trip2. 3 months 30-Jun-07 29-Sep-07 B1

Your colleagues are right. As you didn’t go for another visa and use old petition/visa, your clock is not reset.
