Amounts, dates, and application windows for Yuva Sathi are set by the Government of West Bengal. This site repeats the public outline so it is easier to read, then sends you to the official portal for the record that has your name on it.
If a page on the internet asks you to type an Aadhaar number, a bank account, or an OTP in order to “check Yuva Sathi status,” leave it. That check belongs on yubasathi.wb.gov.in.
