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
