No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
Hi thanks for looking. Non-resident alien here, with an admiration and respect for your fine country. I'll briefly describe my interaction and progress so far under the US financial system. I'd be grateful for some direction on what to do next, and my goal is to eventually be approved for a Chase Sapphire Reserve with a reasonably high limit so I can make proper use of it on my frequent travels.
In mid-2020 I opened a checking account through the friendly internal international referral scheme of my bank at home. A few months later they granted me a Mastercard with a limit of $7k. Early 2021, in a similar way via an existing international relationship, I took out an Amex card with a limit of $9.5k. I've only used the Mastercard occasionally, but have used the Amex card pretty much every month, even if only tiny recurring purchases. Both cards have always been paid in full and early. The Mastercard never had a balance above $300 for even a day, but the Amex has occasionally got up to about $3k albeit only for a week or two before being cleared early. Both cards still have their original limits. I've never applied for limit increases, nor have I been offered any.
I knew that in theory I could/should be building up a FICO score, but that without a US address, SSN or ITIN, there'd probably be no way of seeing it or doing anything with it. I therefore decided to spend a little time and effort in the last couple of years trying to develop my situation. I now have an ITIN, a paid mail receiving address, and a US mobile number. Long story short, for the last few months I've been seing my FICO score being pulled and shown on my Mastercard statement. Anyway, when I first started seeing it about five months ago it was 747 I think, and this month it's 765.
I think the big test now will be whether I can pre-qualify for a card with a provider that I won't have a leg up with due to an existing international relationship i.e. as a completely fresh new customer, but I'm a bit nervous about potentially not making the best choice due to a lack of experience. In addition to general direction/advice, I'd also be grateful for answers to a couple of questions to improve my understanding of the system.
1) I've been reading that in the US 30% is the rule of thumb, and that the lower the better/the average person with an 800+ score only has 11% utilization etc. Is this 30% rule just for people who let a balance roll over month to month, or does it also apply to not keeping a balance above 30% on the statement issue date? If I always pay in full and early, does it matter if I spend a lot of my limit each month?
2) As far as I'm aware, my ITIN hasn't been 'attached' to my credit profile yet. Is there any way to do that, and would it help improve the score over time?

Your credit score at any given point in time will be highest when you only have one credit card reporting a balance under 9%, preferably 1%.
But you don't get any credit score building benefit for keeping utilization low other than the fact that your credit score at this very moment in time will be as high as it can possibly be. So you don't need to worry about your utilization really. Pay your statement balance in full by the due date and you're all set.
What I believe most people (here) would reccomend is trying to only have one card reporting a very low statement balance on your credit report if you're getting ready to apply for something so that your credit score is as high as it can possibly be.

Welcome to the Forum
Fico looks at the highest individual revolving card balance reported as well as reported aggregate revolving utilization. For optimum scoring it's usually recommended to not let any individual card report a balance over 29%, and aggregate reported utilization over 9%. Charge cards like Amex, Green, Gold and Platinum aren't factored into revolving utilization.
As far as your spending, as long as you continue to build positive payment history by paying the balances in full every month, feel free to spend as much of your limit as you want on your cards. This type of behavior consistently over the course of several months is often rewarded with automatic credit limit increases. As @GZG said, unless people are planning a major purchase such as a home, or car, there's no need to micro manage scores.
As for attaching your ITIN to your credit report, You can do so in but believe it has to be done through the mail with each of the credit bureaus, but I don't believe there's any score benefits in doing so.

30% aggregate revolving utilization isn't good. There's no 30% rule in aggregate utilization.
30% utilization for an individual card is an important dividing line. 30% or higher gets you penalized, so it's best to keep each individual card at 28% or less.
2) As far as I'm aware, my ITIN hasn't been 'attached' to my credit profile yet. Is there any way to do that, and would it help improve the score over time?





























Adding an ITIN won't improve score nor does adding work history. So why bother!
In the era of hacking less info on file is better, imo, unless there is value add.
Firstly I'd like to thank all of the kind people who took the time to share their knowledge with me and offer a welcome. It is much appreciated.
Maybe it's because I'm new to the forum, or I need a pair of glasses, but I couldn't find a button to just submit a general reply/it looked like I needed to quote somebody to say something further. So in the order that you each posted, other than my thanks, here are my specific replies to each of you:
GZG: That's very useful, because in perhaps a year or so when hopefully I'll qualify for my objective (Chase Sapphire Reserve) I can gear my spending to match what you said, in the lead up to the application. How many months would you recommend, prior to that application, that I ratchet down my utilization to only have the one card reporting close to a 1% balance?
SouthJamaica: Duly noted, I'll be sure never to let a statement date fall with a balance on any card in excess of 29%, at least until I meet my objective. If and when I hopefully obtain my desired card, then I'll not be so concerned with my score unless I'm given a restrictively low limit. But if I understand correctly from what JoeRockhead said, in that scenario I could just keep spending up to the limit the first few months and hope to be given an automatic increase in due course.
Thomas_Thumb: I believe those are very wise words, and as somebody who generally guards their personal data I very much appreciate what you said. I've been affected, but fortunately in a minor way, by three corporate data breaches in the last ten years.
