I know that Chase will not give repeat bonus miles for the same exact credit card product. So I have started to apply for the other Chase United Mileage Plus Visa cards.

I have a United Mileage Plus Visa (got the 20,000 miles last year).

I just got approved for the United Mileage Plus® Gold Class Visa® card with 20,000 bonus miles (first year fee waived).

I want to apply for the United Mileage Plus® Platinum Business Card with 25,000 bonus miles (first year fee waived).

My question - Do I have to wait between credit card applications (similar to the Citibank/AAdvantage 60 day wait period)? Can I apply and get approved now?
