Can you give an example of what you are doing and what you are getting?

Are you talking about the REST API? Find does restrict results only for the USA when you pass in sourceCountry. Currently the suggest API doesn't support sourceCountry as a parameter so it will not restrict suggestions when passing in sourceCountry.
Suggest doc:

Find doc:
http://resources.arcgis.com/en/help/arcgis-rest-api/#/Single_input_field_geocoding/02r30000001500000...
As you can see, the parameter exists on the Find method but not the Suggest method.
