2.can we show the family vocation tickets to india which was around 3000$ for the year 2010 ,if I go for itemized option while filing tax returns.

You CAN claim your son as a dependent because he did spend SOME time in the United States in 2010.

You CANNOT claim the vacation tickets as a deduction.

If you need professional help filing your return, email me at [email protected] or [email protected].
