请教大家 我拿到了2个月的旅游签证,但是有这么一段话:this visa expires 2 mouths after first arrival .when entering nz ,stay is subject to grant of permission .you must leave new zealand before the expiry of yor visa or face deportation.the holder shall not undertake employment in nz.the holder shall not study for more than 3 mouths in every 12 mouth period in nz .evidence of financial support not required..请问这个签证是不是不可以转成工作签证或学生签证? 如果有中介可以办理 请联系我.谢谢 qq 7563444
