请问8老师，根据国家签证中心给出的通知，需要交费用。里面包含主申请人和家人的费用。如果家人这次不想去签移民签证，该怎么办？是否写信告知移民局取消他们的名字？-If nobody wants to immigrate into US, just write letter to NVC to withdraw the case. Don't need to pay any cents. If only the primary applicant wants to immigrate to US, he/she can submit his/her application (DS 260) and pay his/her fee only. 还是只付主申请人即可？非常感谢您的帮助！
