I understand from your question that you have been charged with "possession" of marijuana. In your situation, you should consult with an immigration attorney. Intent to distribute and possession of paraphernalia are very very serious charges for immigration. So make sure that you haven't been charged with any of those additional charges. What the officer told is not really relevant, but instead, what the actual charges are against you, is what really matters. These charges (if the state charges you with those) can also result in removal / deportation, so it's important for you to consult with an immigration attorney. When you apply for citizenship (naturalization), you have to show that you have "good moral character". The immigration law, INA Section 101(f) provides a list of who is not a person of good moral character. The list includes a person who: Has violated any law of the United States, any state, or any foreign country relating to a controlled substance, provided that the violation was not a single offense for simple possession of 30 grams or less of marijuana... So even though, technically you can apply for citizenship with a single conviction for possession under 30 grams of marijuana, since there are other charges you may have, you should consult an immigration attorney.
