I have the most minor drug conviction, was wondering how serious the US is with this, is it just something you gotta keep re-applying for until your lucky enough to get someone who doesnt care or do they usually look past it, or shouldnt I bother at all?Some travelers are not eligible by law to enter the United States. These include people with certain serious communicable illnesses, criminal records (particularly those involved with drugs), previous deportations from the U.S., certain visa refusals and other problems with U.S. immigration laws or visas.
