CreditKarma Transrisk Score: 715, Vantage Score: 770
I moved to US about an year ago. I carried 3 cards when i was living outside US - a platinum Visa, a world mastercard and Amex. When i was moving to US, i researched and found that only Amex allows you to transfer or get new card in US based on global credit rating. I took Costco credit card because i guessed that a lot of money in the first year would be spent setting up operations here. I guessed correctly. In 9 months on executive membership, we got over $100 cash back and currently on track to get $400 on Costco Amex card for the first year. I always pay off entire balance. Because of my pre-US credit, they gave me a $8000 limit when i applied for the card. Really helped me during the setup time.
The Amex credit card website is the best amongst the ones that i use. I use my tags and it gives a good reflection of how i spend my money. The service representatives are great and respond quickly when i call them. I didn't know the origins of one transaction and when i called, they responded within 3 mins. Moreover after the first 8 months, i got a bump in my credit limit to 9.4K. Extremely happy
