It is all semantics at this point. H-1B is a dual intent visa. It is a working visa with the option for the holder to be sponsored for a green card. (through work, or family). If the person doesn't want to apply for Green Card (Permanent Resident), then he/she are considered a temporary high skilled worker. If they do apply, then yes. They are 'immigrants' until they get naturalized, aka, become us citizens, as their intent is to immigrate in the us. In comparison, holders of F-1 (student visas), B-1 (business visas), are not considered immigrants, as they are supposed to return to their own countries after finishing their studies/work/visiting.
