After more than 183 days within the US territory, I would like to change my W-4 to fit my current situation: working in the US with a H-1B visa, that is, resident alien, and my spouse has the H-4, lives here with me in the US and does not work (she is my dependant). No children.
Can anyone explain how many allowances can I clain and what should I put on my W-4?
