刚刚拿到公民，想给父母办理绿卡，因为父母要过来探亲，所以打算他们来了之后就办理。
485 Application Type应该选a 吗？
a) An immigrant petition giving me an immediately available immigrant visa number that has been approved (Attached a copy of the approval notice, or a relative, special immigrant juvenile, or special immigrant military visa petition filed with this application that will give you an immediately available visa number, if approved)
我没有父母教485的时候没有immigrant visa number, 要提供什么证据啊？
万分感谢！！！！
