You mean you got an invitation letter that said 3 weeks? It doesn't really matter. You can always change your mind and stay up to 6 months unless the immigration officer has limited your time as you entered. Sometimes they will do that, for some reason, they may limit your time a shorter period and then you must leave once that period is up.
yes it says 3 weeks cause that what everyone said to put, we would've said longer but this is unwise yes? anyway I understand u, good to know I can change my mind. thank u. ur very helpful
