Thanks @JournalismApplicant! I received a mail from my programme director on the 9th of March. I'm still waiting on the formal letter from GSAS before I burst out the bubbly. I reckon the Magazine guys get their admits earlier than CRC. Btw a lot of respect for applying for CRC, I didn't have the guts to do it. Hope you get in
Yeah it wasn't an interview. I just freaked out and thought it was more important than it turned out to be. Poor social skills and very little gumption ? 

Hi youngim, I think what you're asking about relates to whether you have a multiple entry visa or a single entry one. As far as I know, you can travel to your home country and back as long as you're carrying your passport, visa and I20, provided your visa is multiple entry (marked with an M or MULT under number of entries). I think most students have that anyway! 
Hope this helps :)
 

Hello! I'd say you have come up with one rather strong rebuttal and one rather weak one to the arguments put forth by the author. 
But I'm replying to you mainly to say that this section on the GRE is rather complex and requires practice, and we're all grad/ Ph.D students like you! What do we know? ? It's more like a critical thinking exercise than a writing one, and I feel you'd be better off asking a professor for feedback. And read writing tips from good guides like Barron's or Princeton. Oh and the official GRE guide too. Topics for these essays are posted on the official GRE website anyway, so be sure to look that up. 
Hope I helped! Good luck
