tinker, one last question/s because i still not the idea yet..i just want to make this one clear..

Q1 - if i work in comp x and transfer to comp z, my former company will be the one to give me borrowing card, right or wrong?

Q2 - so since the borrowing card is valid only for one year, what will happen if - should i say - i like now my present company? can my former comp deport me? i'm i still under their mercy or it's my present comp who is responsible for me now?

thanks..
