Depending on how things play out, the Canadian citizen could also have an immigration case to worry about.
"#DeportBieber" trended on Twitter last week, with critics pushing authorities to send the teen pop star north of the border after he was arrested in Miami Beach, Florida, on suspicion of drunk driving, resisting arrest and driving without a valid license.
It's not likely Bieber will be kicked out of the United States, immigration law experts say. But even so, criminal charges could complicate things for the 19-year-old singer -- and if he's charged with and convicted of any drug offenses, that could change the equation.

What crimes lead to deportation?
In addition to the charges he faces in Florida, investigators in California are also weighing whether Bieber will face a felony vandalism charge tied to an egg attack there.
Immigration lawyers say convictions on those charges wouldn't generally lead to deportation for someone like Bieber, who has a visa allowing him to legally live in the United States because of his "extraordinary ability" in the arts.
That's because those charges aren't considered to be aggravated felonies or crimes of moral turpitude -- the two types of crimes that federal law defines as grounds for the deportation of non-citizen immigrants.
And according to federal law, only violent crimes and sentences longer than one year result in a re-evaluation of a person's visa status.
Translation for those of you who aren't legal eagles: Bieber's probably not going anywhere.
But when it comes to deportation proceedings, it's not a simple matter.
"It's a very complex area of immigration law," said Annaluisa Padilla, a California immigration lawyer.
An "aggravated felony" sounds severe. And often they are; crimes like murder, rape or sexual abuse are among the violations that fit that description.
But crimes that might sound less serious to the average person can also be considered aggravated felonies.
In 2000, for example, a federal appeals court determined that a man with a green card was an aggravated felon after a misdemeanor conviction for stealing Tylenol and cigarettes, according to the Transactional Records Access Clearinghouse Immigration project at Syracuse University, which follows immigration trends and statistics.
Sometimes, Padilla said, a crime considered a misdemeanor at the state level is viewed as a felony by federal immigration officials.
The bottom line: Until investigators finish weighing their options and the criminal case against Bieber proceeds, it's impossible to predict how his immigration status could be impacted.
Drugs could change the equation
After his arrest in Florida last week, Bieber "made some statements that he had consumed some alcohol, and that he had been smoking marijuana and consumed some prescription medication," Miami Beach Police Chief Raymond Martinez said.

Since then, breathalyzer tests have suggested Bieber was not too drunk to legally drive when he was pulled over by Miami Beach police early Thursday. But it could be two or three weeks before tests that should give a more accurate blood-alcohol reading and could tell if he was high on pot are back from the lab.
