After you create a pull request, you can ask a specific person to review the changes you've proposed.
Pull request authors and repository owners and collaborators can request a pull request review from anyone with write access to the repository. The requested reviewer will receive a notification that you asked them to review the pull request.
If you request a review from a specific person, other people with read access to the repository can still review your pull request. If the requested reviewer does not submit a review, and the pull request meets the repository's mergeability requirements, you can still merge the pull request.
Under your repository name, click Pull requests.
In the list of pull requests, click the pull request that you'd like to ask someone to review.
- In the right sidebar, next to Reviewers, click .
- Type the username of the person you're asking to review your changes, then click their username to request a review.
