Dont think it stops you less mabey if u have had a few and done jail time but I know people who have it on thier record and have no problems getting or using thier passport
A passport doesn't guarantee entry regardless if you have a record or not. It's up to the person you speak to, if they will grant you entry. Of course, it should be something valid but you never now.
A passport is only a document indicating citizenship -- it doesn't guarantee anyone anything. A country has the right to deny anyone entry regardless of travel documents provided.
