It is possible but you cannot work until a work visa petition is actually approved. If you are thinking of a H-1B visa which is the most common work visa, the quota has been reached for the next fiscal year so the earliest that a new petition can be filed would be April 1, 2014 for a start date of employment of no earlier than October 1, 2014, which is when the new fiscal year begins.
