Not sure that changing your name is really necessary to study in America. Why do it? Your Chinese given name is fine, I'm sure.

That said, I really don't like Phoenix, Pilot (sounds like a car or a dog name), Yonette, Chemille, Sordina, or Romika -- sorry!

I once worked with a Chinese American woman named Vivian Wu and she was very fun, talented and elegant.

Here are a few names I like that seem to "go" with Wu:

Natalie
Claudia
Amanda
Saskia
Stella
Natasha
Kate
Sara
Eleanor
Esme
Samantha
Charlotte
Rebecca
Miranda
Emma
Emily
Alyson

Phoebe is the only name I like on your list. Here a few more.
Camille
Janet
Nicolette
Alaina
Martha
Denise
Lindsay
Kyra
Belinda
Evelyn
Felicia
Geneva
Hillary
Inez
Ophelia
Priscilla
Renae
Stephanie
