First off, I wanted to say hi. My names Kevin. I found this forum by googling it. He he I recieved my wife's permenant green card. Right now she is back in China.And has the temporary one,but also has the I-751 fee receipt. My question is. Is her temp. green card still good? Or, do I need to mail her the new permanent one in order for her to return back to the United States? As far as mailing her the perm. card. I am very scared. Scared that it may get lost/stolen through the mail. Thanks Kevin
