Service center에서 lockbox로 다시 transfer할 수 있을 것 같은데요
Lockbox에 이메일을 보내서 신청서가 분류단계에 있는지 확인하는 것이 가능할까요?
Customer Service
Lockboxsupport@dhs.gov can answer questions regarding applications and petitions which are pending acceptance or rejection at the Lockbox, and those which have been rejected. Once your application has been accepted, the Lockbox has no information on the adjudication status. After your application or petition has been accepted by the Lockbox, if you have questions about the status of your pending application or petition, contact USCIS Customer Service at (800) 375-5283 or visit our website, http://www.uscis.gov, and use the InfoPass system to make an appointment at your local USCIS office.
