How long would it take for me to get my greencard?

I will assume for purposes of your question that you are still under the age of 21 and will remain so for the foreseeable future. If your father takes the citizenship test by the end of November and he passes it, the length of time before he can sponsor you depends upon how fast he can be sworn in as a citizen. Some immigration offices will swear in successful applicants on the date of the test. Others will have your father wait until the next swearing in date can be arranged. In the latter case, it generally takes about 1-2 months. As soon as your father obtains his citizenship certificate, he would be able to submit an application for your permanent residence. Dependent upon the discretion of U.S.C.I.S., it may waive the interview requirement. In such case, the processing could take up to 9 months or more because of the slowdown of U.S.C.I.S. in processing the interview waiver cases.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
