KYB for non-US entities onboarding with US platforms

Curious what folks' experiences have been lately with the KYB process for non-US based entities trying to onboard onto US fintech platforms, specifically for trading accounts. It seems like the scrutiny has really ramped up, and understandably so with all the regulatory changes. Are you seeing consistent challenges around documentation for beneficial ownership, or perhaps source of funds verification becoming a bigger bottleneck? Or is it more country-specific issues? Just trying to gauge if our recent hurdles are isolated or a broader trend.
