There is no official Q2 pass anymore. From the MoM website:
"S Pass (A new category of Work Pass which replaces the Q2 Pass with effect from 1 July 2004)
- For foreigners whose monthly basic salary is at least S$1,800. S Pass applicants will be assessed on a points system, taking into account multiple criteria including salary, education qualifications, skills, job type and work experience. A levy of S$50 per month will apply and there will be a 5% cap on the number of S Pass holders in each company based on the company's number of local workers and Work Permit holders."
The site also says that a DP will be issued to S pass holders if their salary is at least $2500 per month. Might want to check that out.
Here is the website.
