Iam on L1 visa workpermit in US, Foreign National, resident alien, (2005-2006) worked from sep-05 to Apr-06 as Single status (ie,. I did not bring my dependents).
Returned to home country in 2006 April, and back to US again in Oct-06 to till date with dependents (ie wife + kids).
I received my W2, as I read from IRS website for filling instructions for W7 for all dependents.
I would like to know what all documents should I need to sent to file for state, federal returns.

Appreciate suggestions/instructions to file for reasonable fee. I did Efiled last year online with reasonable price with single status.

Thanks
