i have a meeting soon for my permanent residency decision

For permanent residence, an applicant is not required to show good moral character although U.S.C.I.S. may deny an application based upon discretion where there are unfavorable factors. In your case, the question is whether U.S.C.I.S. will be able to use its discretion or whether you are barred from immigrating to the States by virtue of the marijuana offense. You say that you had a misdemeanor charge for marijuana and the first question is whether there was a conviction or guilty plea. If the charge was reduced or dismissed, or if the charge was possession of 30 g or less, you would not be barred. If there was a conviction or plea and the amount of marijuana was over 30 g, you would be deportable and would not be granted your permanent residence.  I note that U.S.C.I.S. requires you to bring a certified copy of the disposition with you to the interview.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.
