Thank you @jiejie - that makes sense. One final question because I've seen several answers to this on this forum. In the Intended number of entries box should we check the other box for Visa length and write in 10 Year or should we just check the top box (one Entry box). Ideally we'd like the 10 year visa although we have no immediate plans for more than one trip. The form seems to pre-date the new 10-year visa agreement between China and the US.
