I filled 1040NR-EZ for 2008 through CPA(mail). For 2009, I am using 1040-EZ and trying to e-file the same. But to get the 2008 PIN for e-file, IRS automated system is not giving me a PIN and asking me to use 2008 AGI as 0. Is that okay? Is it because I used 1040NR-EZ for 2008? I appreicate your immediate response.Thank you.
