@nickschnecke , a GreenCard granting makes the holder a resident for the tax year. However , the start of the year depends on the first day of the present in the USA. Thus , if you got your GreenCard on October 10th ( admission date shown on the card ) and you entered the USA on July 1st. of the same year on a work visa , then your Residency begins on July 2nd ( first full day ) of the year.
Here is a doc from the IRS --- Residency Starting and Ending Dates | Internal Revenue Service (irs.gov)
You are eligible for Standard deduction if , and only if , you are a resident for the full calendar year.
Hope this clarifies the situation .
Is there more I can do for you ?
