These services include Canada PNP (Provincial Nominee Program) immigration in British Columbia, Saskatchewan, Manitoba, Ontario, and Nova Scotia; employer-sponsored immigration; business immigration; self-employed immigration in sports and culture; family reunification immigration; study experience immigration; federal skilled immigration; RNIP (Rural and Northern Immigration Pilot) northern remote community immigration; and AIPP (Atlantic Immigration Pilot Program) Atlantic immigration.

They assist with applications for Canadian study permits, work permits (including entrepreneur, start-up, company expatriate), and federal LMIA (Labour Market Impact Assessment) job market impact assessment reports. Their services also cover student background assessments, school and major selection, detailed application proposals, document modification, application submission, communication with schools, and selection of subsequent offers.

The RCIC and the copywriting team are responsible for preparing and reviewing relevant materials with applicants. They submit the applicants' immigration applications as licensed immigration consultants, track the cases, and review the process to ensure that no mistakes occur at any stage.
