i'm a U.S. citizen. when i first came to china, i was here on a z-visa. more recently, i think it switched from z-visa into "residence permit." i notice each time the residence permit only lasts for 1-yr.
1. why? cant i get one that lasts for several yrs? or is 1-yr the limit? i ask this cuz my passport pages are almost filled up.
2. what is the difference between "residence permit" and "D-visa?"
3. if i were to resign from my job, and be jobless (i.e. i have no employer, or perhaps work for myself), what paperwork do i need to apply in order for me to continue staying in China indefinitely? D-visa? or residence permit?
