（1） A photocopy of confirmed onward AIR-TICKET. Itineraries and open tickets are not acceptable. A valid visa for the next destination should be obtained (if applicable).
新加坡面试不管成功与否我都应尽快赶回美国，但我没拿到回美国的签证怎么可能订机票？我还没去新加坡怎么拿从新加坡回来的签证 （visa for the next destination)。
（2） If you are returning to USA after visiting Singapore, please produce a valid US visa or relevant documentary proof confirming your returnability, e.g. INS Parole Paper, etc.
同样的问题，我还没去呢，怎么能拿到回来的签证？
另外，我给美国驻新加坡使馆去邮件问我能否在抵达新加坡后直接在新加坡而不必返回中国申请回美签证，他们回了个邮件给我，说You are permitted to apply for a visa in any U.S. consular district where you are physically present.
