Another issue has come up, looking at the rules for O-X Visa seems my wife who is Chinese could not apply as a dependent, is there any other form of long term Visa she could get?
TLDR : Answer Summary
The inquiry revolves around the inability of a Chinese woman to apply as a dependent on the O-X Visa. Suggestions from commenters include considering the Elite visa, which offers a five-year term, and the notion that she might qualify for her own visa based on financial independence.
