I plead guilty for possessing over 30 grams of marijuana about 4 years ago. My question is can I still be eligible for naturalization? I've been a permanent resident of the US for more than 25 years. I've recently got a new job that will require some traveling abroad, how will this effect my traveling? Thank you for your help

Usually your first arrest are forgivable but some are more serious than others even if it's your first time... Having such conviction in the U.S is serious and you might not be eligible for naturalization since they look at you as a criminal but with great lawyer you may be eligible... Good luck...
