If I could speak any foreign language (esp an Oriental one) as well as she speaks English I'd be pretty pleased with myself.
She's absolutely right about not arguing with foreign immigration officers. Your own in the West - well argue with them any time. Cloggie friend gave AMS immigration a mouthful when ethnically non-Clog tried to question her right to enter Holland.
Recollect one of our BA FEs took his Japanese wife on a BKK trip. They were caught out in a rainstorm and, when they returned to the 'Dusty Fanny' looking a bit bedraggled, the doorman was about to refuse entry to his wife. Much loss of face! Although to whom, I am uncertain.
