She may come to the U.S. under the visa waiver program for up to 90 days only. See 1st site below about the visa waiver program. If she wishes to stay for up to 6 months, she needs to apply for a B-2 tourist visa. Then see 2nd page below and read starting where it says Qualifying for a Visa .....this is where she needs to start . Then, just follow all directions there. She may prefer to use the last site...instructions are very clear there.
