 how long your visa will be approved for, but three months is pretty standard. So that's the longest that most people can go. When I first went, I went for two months, which I thought was really a great way to get oriented. And I ended up coming back for three months consistently. So just to give people a sense. But I mean, if you can only go for a month, if you can only go for three weeks, that's also fine. But just to give people an idea of what we mean by long-term commitments.
