> Is the Kentucky State going to call a school in Bangladesh to verify the transcript? Wealthy people who can afford to send kids to school in US with full tuition can probably find a way to "buy" a good transcript from a local school. Maybe you meant that SAT is a requirement, then yes, it thing might have changed and it is more challenging.

They often do. And admission committees learn from experience: if they admit students from a school and they don't perform well, they recruit less from that school the next year. Conversely, if they have students performing well, they will continue to admit more. There is a chain of trust.
