急急。。。student visa問題 （已回答）

lama

請問大律師，我收到移民局的email說，因為06年酒駕，但是一直在申請表沒填上，但是我真不知道要填的，他現在說我 You have failed to declare criminal convictions on your application; andYou have withheld material information from Immigration New Zealand and as such you do not meet character requirements to be issued a student visa
他現在要求我解釋，這個會很嚴重嗎？還有我應該怎樣解釋呀？還有甚麼是character waiver? 謝謝
