Query 1 :-
I came to US (first time) on 2nd April 2006 on L1 with my wife. I am in US since then. I believe my status will be resident alien. For Jan to March 2006, I have Indian Income (Salary) & Indian tax deducted on the same. How should I mention the deducted Indian tax while filing federal return? Does any software support Foreign Tax Credit feature ?


Query2:-
I am in the state of Louisiana since the time (April 2006), I arrived in US. In this case, will I be considered part year or full year resident of Louisiana? Does foreign income/tax has to be mentioned for filing State tax also?

Actually you are dual status (and should file a dual status return -- see publication 519). BUT you may elect to be residents for the full year in which case you must report your income from India as well (and yes, then claim a foreign tax credit).
