My girlfriend may need to travel to Guam from work. The two options of getting there is flying through HNL or NRT.
If she flies through NRT does she need to go through Japanese customs and thus need a passport with her even though she is just passing through with her final destination being US soil?
If flying to GUM via NRT, she will NOT need to enter Japan. No need for Japanese customs and immigration. She will need to clear transit security in NRT.
She
will need to have her passport with her. As, she will "re-enter" the USA in Guam and go through US Immigration and clear customs upon landing in GUM.
Same with her return flight via NRT. Just transit security in NRT and then clear US Immigration and Customs upon return to the US Mainland.
If she goes via HNL, she will need to clear Guam Customs upon entry into GUM. There is no immigration check in GUM. I believe that no passport is necessary.
On the return, upon landing in HNL, she will need to clear US Customs in HNL. There is no immigration check in HNL.
