Because you are an Indian citizen, you get to claim the $5,000 standard deduction. Further, you may claim your spouse. Download a W-7 from
www.irs.gov and fill it out to apply for an ITIN for your spouse. You enclose the W-7 with your tax return and the IRS will issue the ITIN and enter the ITIN on the tax return for you.
Be sure to mail your tax return (which will be Form 1040NR) to the IRS Center in Philadelphia, Pennsylvania.
Finally, you also need to file Form 8843 to report your visa status as an exempt individual.
