父母绿卡申请求助 要求补件 7年前的延期记录 请问哪里可以查询记录？ 绿卡申请要求2013年的一次延期提供补件，记得当时收到一份邮寄的I-797同意延期的信件，这份纸制件他们在之后还来美国的时候还使用过，合法入境的。可是现在父母已经找不到了。目前需要我们提供 Submit copies of travel dociments you used to enter and exit the United States between XX-XX. These include: 1. copies of passport pages that have U.S. visas, 2. Form I-512, Authorization for Advance Parole, 3. Form I-94, Arrival-Departure Document, 4. Approved Form I-539, Applicatoin to Extend/Change Nonimmigrant Status, and 5. Receipt/itineraties of travel.

是不是如果能提供I-797那张同意延期的表格就可以了呢？ 或者哪里可以提供查询历史记录呢？
或者找移民律师是不是能有帮助呢？
谢谢.
