Our apps

Small apps for real-life moments.

Simple tools that each do one job well: green card dates, H-1B odds, citizenship prep, job offers and layoffs, health plans, taxes, sending money home, trips back to China and a few for family life.

  • 20 web apps for phone & desktop
  • 1 iPhone & iPad app
  • No ads, ever

The 18 toolkit apps are free, bilingual (English / 中文) and need no account. They are informational guides, not legal or tax advice; check the official sources each one links to.
