I took plea on the charge endagering a welfare of a Charls less than 16 in 2010. This charge has the deportation problem , I am a green card holder. So that I filled 440 motion to vacate my plea, but lower court denied the motion. So I Applealed in the court of appeales , New York states highest court. I don't have to bee here for the appeal, so I want to go back to my country for 2 or 3 years because I have some business there. I know green card holders must have to come to USA every year to renew the visa. But I know that we can apply for 2-3 years visa extension. So can I apply for a 3 year extension by filing I 90 form? My appeal in the appelleate court , so is there any problem to go to immigration office ? If I win my appeal then I can come back to USA.
