Cultural Tip
In Brazil, asking about the length of a visit is considered polite, especially when you’re offering hospitality. Adding “por” (Por quanto tempo) sounds a bit more formal and is common in written or business contexts. Remember that “ficar” can also mean “to become,” so the meaning is clear from the context of a stay.
