I'm 21 year & want to leave parents house

1. IF you have attained 21 years, THEN "legally" you do not require permission from anybody, including your parents.

Once you are a major, you can decide on your career, but if your parents are senior citizens then they may seek maintenance and care from you once you are settled abroad.  Without parent's support, it is most difficult to do any venture at your age and society may not approve your desertion of parents, if your presence is required by parents at this stage.   Convincing them through elders is a better solution.

If you can manage your expenses and are not dependent on your parent for any reason or any material thing, then you can very well proceed with your proposed higher education at a foreign country. 

They cannot stop you from proceeding, if at all they don any mischief this way, you may approach police with a complaint on this harassment and illegal confinement etc.
