Resume conventions vary by country. The CV you'd send in India, the UK, Germany, or China is structurally different from what a US recruiter expects — and most of the differences quietly kill applications before a human sees them. Photos, date of birth, marital status, full home address, three-page length: all standard in many countries, all immediate disqualifiers in the US.
This page is the cleanup pass. What to remove from a non-US-format CV. How to phrase your work authorization status without overcommitting to a sponsor or undercommitting to your eligibility. Which US-specific conventions matter, which ones don't, and where to put the visa-status line so recruiters find it without it dominating the page.
