I'm an international student and want to apply for Apple Card

You need to have a Credit history for Goldman Sachs to review before they'll approve the Apple Card for you, which means a steady income, and more importantly a Social Security number.

You may not be able to get the card until such time as you are a legal resident not a student, and you have the required information for them and have generated a Credit History that qualifies you for the Card.

At this time even if you could apply, Goldman Sachs will likely decline you.
