LONDON (AP) - First Lady Michelle Obama has met Queen Elizabeth II at the start of a state visit and will travel to Oxford to speak to students there.

Obama shook hands with the queen at a Buckingham Palace ceremony, reminding some of an earlier meeting when she affectionately touched the queen's back in a minor breach of protocol.

The first lady also planned to attend Tuesday's state dinner at the palace.

She plans to travel to Oxford on Wednesday to speak to London students spending a day at Oxford as part of a program she has supported since her last visit to England. The students are from the Elizabeth Garrett Anderson school, which Obama visited in April 2009.

The Obamas are staying at Buckingham Palace during their brief visit.
