Overstay & ECC CheckerHow long have I overstayed — and do I need an ECC?
Enter your authorised-stay date and visa status to get the days overstayed, chargeable months and approval level, plus a separate ECC verdict. The ECC is where most people slip: a stay of 6 months or more, or a visa that has expired or been downgraded — either one is enough to trigger it.
