I hope not. The USA can not support that kind of growth and still maintain what is call the "American way of life". Especially since "the America way of life" is not sustainable. China and India have populations that large but the people there consume far less resources. If the USA grows to be 1,000,000,000 people and nothing changes expect to run out of food and water and expect a very sick population with a high mortality rate due to uncontrollable pollution.

Fortunately it is unlikely that the USA population will ever get close to 1,000,000,000, because birth rates are falling and fewer people are moving to the USA.
