An invitation letter by you and the following info should be included: Information of the applicants (full name, gender, date of birth, etc.); information on the visit (purpose of visit, arrival and departure dates, place of intended residence, relations between the applicant and the inviting individual, financial source of living expenditure, etc.) and information of your wife and kids(name, contact number, address, signature, etc.)
3. A photocopy of your passport and residence permit.
