International student forgot to file 8843 for previous year
Hello
I have been in the US as an international student since 2005 fall, and am still currently enrolled. I had no income in the year 2007, and didn't file the corresponding 8843 in the year 2008, as no one in our school had told us about it, I have just filed my 8843 for this year though ( as I didn't have any income in the year 2008 as well), what steps do I need to take to file the 8843 for the year 2007? As I don't want it to cause any problems later on whilst applying for my permanent residency.
Thanks
