Congratulations, and welcome to the forums!
Most of your credit card accounts will update to the credit bureaus on their individual statement dates. Not on the due dates, but on the date that they post the statement.
After that, you have to wait for each CRA (credit bureau) to post the new $0 balances. For most of us, EX does this right away, and then EQ 3-4 days later, and then TU a couple of days after EQ.
So all in all, it could easily take a full month for each individual account to cycle through and update.
If you have American Express cards, they take an extra month to update. HSBC/ Orchard bank cards should update around the last business day of the month.

These will give you the background knowledge you need to understand what you read here on the forums.
