>>149382524No. It just means foreigner. It's just the least polite way to say it, but it's not an insult, just not something you'd use in a formal setting.
From most to least formal:
外国籍の方 Gaikokuseki no kata - Person with a foreign nationality
外国の人 Gaikoku no hito - Person from a foreign country
外国人 Gaikokujin - Foreigner
外人 Gaijin - Outsider
