You can work on a DP. You cannot work on a LTVP. If you were not being paid in Singapore, you'd be under the radar. I think there is a thread somewhere that states that someone asked this question and was told it was OK as you are not being employed in Singapore. Just wondering where this thread is...
I don't want to fill up the board with similar posts so I was wondering if any thing else came of your situation? Since it's a company that can not provide you with an LOC, did you have to bail on the option?
