Often the International Student Association at your college or university will arrange ground transportation to pick you up. 

Other options include: 

• Shuttle - A shuttle is a mid-sized bus or van that usually costs around $30-$50 depending on the distance you are traveling from of the airport. If the driver handles your baggage, an appropriate tip is $1-2 per suitcase. If you are staying at a hotel initially, the hotel may offer free shuttle transportation from the airport. 
• Taxi/Cab - Only use an official taxicab; avoid private drivers who promise a good rate. Most airports have taxis waiting right outside. If you are not going very far (10-20 miles) the cost will be around $30-40, plus tip (about 15 percent of total fare). This is probably the most expensive way to travel, but it's also quite convenient. 
• Buses/Trains - Buses and trains stop only at designated stops, so you will only want to use these services if a stop is near your final destination. You will have to handle your own luggage. The cost is typically much lower than a taxicab. Most bus and train services in the US run infrequently or not at all after 10pm, so it is not wise to use these systems if you arrive at night.
