After some back and forth, I finally got approved for the Apple Card with my ITIN. Instant approval for $3000, and they didn’t ask me for ID verification or any extra documents.
For data points, I used Tello roaming data, set my device region to United State , and matched the time zone as well as recommended. My credit history is already over 7 years old, so maybe that helped too. Just sharing in case anyone else was dealing with the same Apple Card ITIN issue.
