Overseas students at certain institutes of higher education are permitted to work while they study. During term time, these eligible students are permitted to work 16 hours per week. Work permits are not required for those who want to work during holidays.
Upon completion of their degree program, overseas students may submit an application for a one-year Visit Pass (Long-Term) to ICA, if they wish to seek employment in Singapore. This can be done electronically via e-VP. Prospective employers usually make this application for you.
As a student pass holder, you cannot get a Dependent Pass [DP] or Long Term Visit Pass [LTVP] for your spouse.Basically, a spouse can only get a long-term pass on his/her own merits, e.g. based on work or can get a three-month LTVP for job-seeking purposes
