HireRight Background Check International

Hi! Recently just got an offer letter with a credit union. Now im in background check with HireRight. My former employer was outside USA. Just want to ask how many days will it take to be completed? My supposedly start date will be in April. Im a bit worried since i don’t have any updates with the HireRight and how does their process work. I think it’s been 7days (including weekend) since i receive the email. Just a bit nervous i might not reach the deadline before my hiring date and worried that my employment will lapse. Thank you for your help 😊
