no

I don't think it's necessary to go abroad for just studying language. However, you'd learn fast and perfect language and culture if you go to the target country. So if you've got a chance to do so, don't let it go. I'm an English major myself and never went abroad. But I'd do so one day. Would love to fit myself into different cultural atmosphere.=)

kakak jerry, apakah kakak dapat berbicara bahasa indonesia,saya tunggu jawabanya ya kak...

but we are still in China. Our language enviroment is speaking chinese. We cannot totally put ourselves into the English-melting pot

I don't think so. World is flat these days, where people are closely connected by internet. Without going abroad, people still are able to immerse himself in English enviroment.
