A Typical Onboarding Timeline

For a straightforward single entity LLC or IBC with clear beneficial ownership, onboarding documentation review typically takes one to two weeks once everything requested has been submitted. More complex structures, multiple related entities, ownership through other corporate vehicles, or trading activity that needs additional source of funds documentation, generally take longer. The single biggest factor in onboarding speed is not complexity itself, it is how complete the initial document submission is; incomplete submissions that require several rounds of follow up requests are the most common cause of delay.
