I cannot find an affordable flight from Taiwan to Chicago except for one about $625 through China Eastern Airline. Instead of it going Taipei direct to US (LA or San Francisco) then on to Chicago, it goes to Shanghai (PuDong) & has about a 18 hour layover there.
Any experience with this route, airline, or Pu Dong airport? Is a transit Visa needed? This is for a citizen of Nicaragua who is studying in Taiwan and got a 1 year B1/B2 US Tourist Visa wanting to visit family in the US for about 2-1/2 months & return to Taiwan for studies.
