HDFC never considers the ICICI Bank credit card limit. If you apply using an ICICI Credit Card, the next concern will be that your limit is only 15k. 🤭
It's better to consider using another card, such as Axis, Amex, Standard Chartered, or SBI, with limits of over 1.5L and then try to apply for a Core card. If your card is approved with a limit of 1.5L or more, using that, you can apply for Tata Infinity Plus.
