請大家幫幫我.....!!

You a happy life in the United States?
Do you live a happy life in U.S.A.?

003 同004 都錯

003 係口語 you okay????
you happy???
you have a happy life in the U.S ??

004 should be
do you live happily in the U.S?
or do you have a happy life in the U.S?

不過美國人可能聽落好怪
佢地問候人 可能係咁 how is your life in the U.S. ?

Do you live a happy life in U.S.A.?

You a happy life in the United States?

Is your life enriched with pleasure in the U.S.?

{ 你在美國生活得開心嗎? }

You can write as:
1. Is your life in US happy? Or,
2. How is your living in US? Are you happy? Or,
3. Are you living happily in US?
