The review process can take up to 48 hours from the time you submitted your profile for review. Once the process is complete, you will receive an email and a notification to your Upwork account to update you about your approval status.
Your profile may indeed end up getting rejected.
But don't assume the process is finished simply because it has been under review for 48 hours.
We're at the start of a long weekend.
The review may be finished in an hour.
Or a week.
I am waiting for account approval from last three days and it is still pending please let me know how much time it will take or let me know if anything is need to add or update in my profile.
