Bill Gates is once again urging US lawmakers to increase visa allocations for skills workers, spend more money on technology, and pump up maths, science and engineering education in schools. 

Gates will testify to the House Science & Technology Committee later on today and is expected to renew his calls for immigration and education overhauls that will help the US stay competitive in the global market.
Last year, the call from Gates was along similar lines, when he called on Congress to welcom great minds into the country instead of turning them away.
Analysts believe he may find his pleas fall on more sympathetic ears this time around.
He also made a compelling argument about early intervention in education, to make maths and science more interesting to younger learners.
