Correct before arrival
Update incorrect IPA particulars before bringing the worker to Singapore or entry may be refused. For name, birth date, marital status and passport number/expiry, business employers use WP Online and domestic-worker employers use FDW eService.
Other particulars use the corresponding business/EA or domestic-worker request form. After the confirmation email, reprint IPA and give the worker the corrected copy for arrival.
