I have contacted the lawyer three times and left messages. Has not called me back

This is not really an immigration law question, if you think about it. If your lawyer is not responsive you should consider the following options: 1. Contacting the lawyer in writing and asking to return to you.  2. Contacting the lawyer in writing and instructing the lawyer to provide you with accounting of the work done vis a vis fee paid.  3. Hiring another lawyer and then going through the step number 2 but this time putting the lawyer on notice that you have another lawyer and would like him or her to stop working on your case.
