I sent my attorney all my documents for NIW petition two months ago. Since then, I have never heard anything about how the petition letter is going on. Evertime I asked him about the progress, he just said he was still working on my documentation, and this taked time. I don't know how long writing a petition letter is supposed to take. I am afraid that he becomes unhappy if I push him too much. But I am also really afraid that he takes me several months but finally give me a poor petition letter. So what should I do. Any suggestions are highly appreciated. Thanks.
