Hello everybody , here is my case :
I'm a permanent resident since 08/02 , I had to leave for 10 months outside USA for reasons of studies ( 11/02 to 08/03 : knowing that before I came to the US I had already spent 2 years in that school and I had another year to take in order to graduate) which technically broke my continuous residency, since 08/03 till now I ve been only absent to US once (02/05 to 05/05) , when do I have to apply
Thanks and regards

The 3 month trip should not affect your application, I would count from the time you came back 08/03
