My experience on this might be a bit outdated (from '08), but I stepped outside the country after a decade and appeared on the H stamping interview in KTM. Nobody raised an eyebrow at the US consulate office. I was questioned by the official at Delhi PoE, however-- (I had a long transit and decided to get out of the airport!). I told him if there was a problem with me entering India due to my protracted stay in the US, I will return to the transit. He said he was just curious!
