过两天要登陆了，查了一下要求，发现很麻烦，好像没有这么麻烦嘛？
Make sure you have the required documentation: title documents, registration, sales receipts, statement of compliance label and manufacturer's recall clearance letter.
我没有sales receipts。
U.S. Customs requires notification of all self-propelled vehicles being permanently exported from the United States. Their regulations state that at land border points:
1. The required documentation must be submitted to U.S. Customs at least 72 hours prior to export; and
2. The vehicle must be presented to U.S. Customs at the time of export.
U.S. Customs recommends that you contact the port of crossing directly to determine exact documentation requirements and hours of operation.
没有听人说过。
请大侠指教。
