Ok, better chance also if ur sis can sponser you, as is one of the conditions of a visa to come here, that you will need some kind of sponser who can take care of you financially.
The said sponser will also need to provide evidence of financial solvency, for example, she will need to submit bank statements, and pay slips to the Embassy.
Trust me, I have done it.
The very best of luck.
