You can file jointly with your wife and you both CHOSE to be treated as resident aliens. This will allow you to claim the $11,400 joint standard deduction plus two $3,650 personal exemption (for yourself and your wife).
You will need to submit Form W-7 to apply for an ITIN for your wife. A notarized photocopy of her passport needs to be stapled to the W-7. You can get the photocopy notarized at any local bank or, failing that, at your local IRS office.
