In one of the seasonal quests there was a Far Eastern merchant who stated she'd been coming and trading in Eorzea for quite some time. There are quite a few other seasonal events where residents of Othard have come to Eorzea for a time. So it's more than plausible for Far Easterners or Domans specifically to have come to Eorzea prior to the razing of Doma at the hands of the Empire. Limsa Lominsa trades globally, after all, so Far Eastern merchants are likely commonplace there.
But if you're referring to the very specific group of Domans who arrive as part of the MSQ, those have only been here for a few months.
