The new sponsorship law (Law Number 4 of 2009 regulating the entry, exit, residence and work of foreigners)stated:

Workers are allowed to sponsor their wives and sons up to 25 years of age and unmarried daughters of any age.

A freshly-arrived worker has to report to the authorities concerned (the department to be identified by the Minister) within seven working days of his arrival here. The responsibility for this also lies with the worker’s sponsor.

Those arriving here on visit visas sponsored by hotels can stay with their relatives and friends provided they inform the authorities concerned within 24 hours of their arrival.

Housewives and children of workers are exempted from the exit permit rule. They can travel out of the country without producing an exit permit.

Similarly, visitors on a 30-day visit visa are not required to report for health checkups and finger printing. They also do not need an exit permit to leave the country.

Women in independent jobs can sponsor their husbands and children.

Asked your mandoof on what is the documents needed and procedures. As I understand, the immigration department always changing their procedures/requirements.

Good luck!
