Japanese expat in Georgia – built a personal project for Japanese expats struggling with US credit cards

Hey everyone!

I’m a Japanese expat in Georgia (family of 5) and like many of you, I spent way too much time googling basic questions about US credit cards that nobody had answered in Japanese:
• Can I get a card with no credit history or SSN?
• What’s the Chase 5/24 rule?
• How do I transfer points to ANA/JAL miles?
• How do I build credit for my spouse?

So I built a small tool for myself – and then thought others might find it useful too.
USCardNavi (see my profile) – free, Japanese-language only:
• 5-question quiz → personalized card recommendation
• 11 cards compared (including JAL USA Card & ANA CARD USA for zero-credit-history situations)
• AI chat in Japanese for individual questions
• 5 blog posts on expat-specific topics

It’s rough around the edges but functional. If you know any Japanese expats in the US who might find it helpful, I’d appreciate you sharing it.
Also genuinely curious: what financial questions did YOU struggle with most when you first arrived in the US?
