Conversation Between Immigr8 and s3_b3

I am in US from 27th Aug 2010 and getting per day expense from my company. This is not as a salary, I am still getting the salary from my same employer in India. With this arrangements, I am not paying any tax to US. If I plan to stay for more than 183 days may be for 10 days more would I or my company needs to pay any tax to US government? I am expected to travel back to India but I wish to be on PTO (leave) for 10 more days (after 180th day) to see places around in US. Can I do this? Or I have to go back to India on 183rd day? Any help would be really great in this regards.

Apart from the L1 visa, I also have B1/B2 valid for 10 yrs and expiring on 26th June 2016.

Can you help in this?
