I do not endorse applying for an ITIN or using it to apply for and use US credit cards. I only organize the information here for my own interest and do not guarantee the accuracy or legality of any of the steps taken. There is a very, very long thread on RedFlagDeals full of people discussing how you can apply for an Individual Tax Identification Number (ITIN) and use that number to apply for a US Credit Card whenever you’re asked to provide an SSN.
