You could review your options after you get the Revit language as shown here:
That said if you’re doing a workflow which frequently works across languages within your office you may want to consider adding a UI element to allow the user to select the parameter they want to work with directly. That or make a list of what the parameter name should be in every language you use, and use that as a dictionary to get the right result.
I believe the Revit language packs may also allow you to resolve this in another way.
