MEXICO CITY (Reuters) - Microsoft Chairman Bill Gates, the world's richest man, said on Tuesday the United States should reform its immigration laws and give more flexibility to higher-skilled foreign workers.

Speaking at a conference in Mexico, the birthplace of millions of immigrants to the United States, Gates said reforms "would be helpful so we are predictable, so we are clear."

"I'm a big believer that as much as possible, and there's obviously political limitations, freedom of migration is a good thing," Gates told reporters.
