<p>Preetsingh,
As a U.S. citizen you do not need to get an invitation to enter the U.S. and enroll in a community college in California. Just pack your bags, make sure your U.S. passport is still up to date(If it is expired just take it to the U.S. Embassy or an American and they will issue you a new one), get on a plane and fly to California. you can then go to any community college in the state since community colleges have no entrance requirements. You could probably start school during the summer sesion. Try to get California resident status. It will lower the tuition.</p>
