Cannot get the standard deduction for my nonresident spouse with a it in number

[Hcj322]

This year IRS did not allow me to get the standard deduction for my nonresident spouse that has an ITIN number. Is this due to new tax laws?

I looked at a flowchart last year which indicated she was eligible.  Do I need to challenge IRS?

Where can I find a complete writup of the changes in the tax law which disqualifies her.

nonresident aliens are not eligible to use the Standard deduction on form 1040NR or 1040NR-EZ with very few exceptions. Please state your visa status and since when  you are both in the US
