Yup the free premiere currently is only for "resident of the United States (excluding Hawaii, Guam, Puerto Rico, and the U.S. Virgin Islands)". Full Terms and Conditions of the offer you can find here: Stadia Premiere Edition with Purchase of Game for $29.99 or above Offer Details
In some countries there are some discounts though on Stadia Premiere edition, so I am living in UK for example and in the Google Store you can get it for 20 bucks atm. So you can also check if this is the case for you, just go to store.google.com and select the Premiere edition.
