I dont think there should be any problem since your employer is Dhoti Consultancy. How immigration can know that you are in project or not? There is no way to know that and the documents describes itself that you are employed to the Dhoti Consultancy and By Law, if you are in US, they should keep paying you the salary. There is no bench period law in US. So get all the documents and come to US. You might also want to bring the vaccation letter or something like leave letter that u might have while getting back to Nepal.

So my suggestion is that there should not be any problem. You can also get free consultation from immigration lawers in USA.

Good Luck

Hi, I had same situation like urs. My project got over on Dec 2008 and left for Nepal on Jan, 2009 planning to come back on end of Feb. So before i came back, i called my employer to make sure everything is ok. But they told me to stay in Nepal and start marketing. I said ok and didn't say any single words. But i knew that, there is no way we can get project staying in Nepal. That too we used to have 16 hrs power outage. So withing saying any single word to my employer and returned back to US. But i did one biggest mistake informing my employer that i am back. I shouldn't have done that as they have sent me an termination letter with in week. But fortunately, i  transfer to another employer and thanks to God, it got approved. To be frank, i didn't have job at that time.
