我是一名在德国读书的留学生，申请到了暑期在新加坡的实习位置，公司给我办了In principle approval letter for training employment pass.
我已经收到了email件，看到信上说： "This letter contains a pre-approved Single-Journey Entry Visa for entry into Singapore. To use it, the pass holder should produce a copy of this letter to the Duty Officer at the immigration checkpoint."
