I just posted the question below: I would just like to note that I will be traveling to South Korea during that period, not to the US. I am a US citizen.

Hi, I am currently in China and have a multiple-entry 180day student visa. It expires at the end of march 2011 and it says I need to enter before Jan 21, 2011. I plan to get another 180day extension in late feb/early march so that I can stay until June 2011.

I already entered in Sept 2010, would like to leave the country AFTER Jan 21 2011 and return in early February 2011 (so leave AFTER the enter China date and return later BEFORE the visa expires, will I have any problems doing this? Does it mean I will have to change my visa? Will I have to pay much more?
