How long did it take you to stop feeling like an outsider in a new lab in a new country?

Just curious. I started a postdoc in a new country almost 2 months ago and still feel like an outsider in the group (in general, not work-related). I try to socialise but as a somewhat shy person, I tend to just listen mostly to other people telling stories, sharing opinions, ideas etc at the lunch table. There’s also so much cultural gap! So just wanted to know from people who moved countries/continents for postdoc, am I the only one or did it take a while for you to integrate as well?
