I do know, it is the LAST piece of paper that needs to be processed by the US government.
I do know, it the last piece of paper the Chinese government needs before they issue travel authorization.
I do know that means we have...
then... Travel Authorization.
We should have our TA in our hands in 2-4 weeks. Which means we are on schedule to travel right after Chinese New Year. Even if we get the TA in 2 weeks (or less), for various reasons, we will have to wait until after Chinese New Year to travel.
So, we expect that we will travel mid-February. Hopefully we don't have any bumps in the road between now and then.
