Yes its fairly simple process..
1) Visit CTS branch providing 'Home Return Permit' (Cant't recall if you need to book appointment, better call and confirm)
2) Fill-in simple form (You will need help of someone who can read/write Chinese as forms are/were only available in Chinese, In my case officer was quite helpful)
3) Take photograph in one of the booth (Do not rely on standard pp size photograph, they have some strange requirement e.g. can not wear glass etc)
4) Submit the form and get acknowledgment
5) Collect the card after few days (Not sure how fast they process these days for first time applicant)..
