Deductions & credits

Thanks. Hope this will not create other issues.

Also, I can still claim a standard deduction for my wife (adhering to my current situation). Right?

1. If yes: I have my SSN. Do I need to do something else for claiming her as a dependent? Like fill some other forms, get an ITIN form myself as Head of Household. Or something else.
2. If no: What other type of tax benefits I can get for her?

Thanks
