You will not need a new remote for this as GitHub will store a copy of
the branch submitted in the pull request in our repository.
Check the GitHub documentation here:
You can also use the hub  wrapper around git to make such things
easier. This tool implies all repository URLs will point to GitHub. For
example, the command
hub remote add raimue/ports
would add a new remote named "raimue" with the URL for this repository
Even better, many commands will just accept references to commits or
pull requests on GitHub. For example, you can directly switch to a local
checkout of a pull request with a single command:
hub checkout https://github.com/macports/ports/pull/42
Also works similarly with 'hub cherry-pick' or 'hub am'.
Although I do not like their proposal to alias git to hub, as I like to
keep control what extensions I use with git. I prefer to explicitly call
hub when I want to work with GitHub.
 https://hub.github.com/ ; 'sudo port install hub'
