Deductions & credits

Hello 

 

I am very new to Contracting, I've been overseas since April 1st. I will be paying taxes in the country I will be working in. I would like to file exempt For united states taxes, so my question is am I eligible for form 673 and to be exempt from united state taxes? and if yes, what portions do i fill out.

I really do not want to end up owing the united states. Please help. i have no idea and i am very new to contracting. thank you so much
