Document ChecklistのSUPPORTING DOCUMENTS FOR SPONSORED PERSONSの7のところですよね?
2019年3月から様式がまた変更されています。
a)申請時現在同居していない場合の提出書類の1つ目が2人の手紙やチャット等のやりとりです。
「Proof of Contact: Provide letters, printed text messages, emails or social media conversations, or other documented proof of contact between you and your sponsor. Provide a maximum of 10 pages with your application.You must provide certified translations in either English or French of all proof of contact documents that are not already in English or French.」
ここでは英語と仏語以外はcertified translationsが必要とのことです。
これはコモンローの場合ですがcic.gc.caに2人の関係を証明するものとして載ってました。
shared ownership of residential property
joint leases or rental agreements
bills for shared utility accounts, such as:
gas
electricity
telephone
joint utility accounts
important documents for both of you showing the same address, such as:
driver’s licenses
insurance policies
identification documents
You don’t need to include all these items to prove your relationship is real. We may consider other proof as well. Use the document checklist to find out what to submit with your application.
We don’t return photos, telephone bills or letters. Don’t send videos or CD-ROMs. We’ll return original documents such as marriage certificates and passports. However, you should send certified photocopies unless your checklist or country-specific requirements ask you to submit originals.
