Hi all

I have come to USA on an L1 visa ( Intra Co transfer ) and my payroll is being managed by the US Sister company , My in come is quite less ( <65k annum ) . Is there any way I can save on taxes ? Would it help if I invest some money in my home country ? Am I eligible to file 401k ( which I think is the retirement plan ),, please let me know

Thanks in adv
