Many couples assume the hardest part of spousal sponsorship is proving the relationship or passing medical and background checks. But for in-Canada (inland) spousal sponsorship, a large share of applications never even enter processing because they fail the first screening step: the R10 completeness check.
An immigration news report, citing IRCC operational data for January to October 2025, estimates about 27% of inland spousal/common-law partner applications reviewed in that period were returned as incomplete (failed R10). The practical lesson is clear: the fastest “win” in spousal sponsorship is submitting a complete package the first time.
This article explains what R10 is, what IRCC checks at this stage, and the most common completeness mistakes that cause applications to be returned before they receive an Acknowledgement of Receipt (AOR).
What is the R10 completeness check?
R10 refers to section 10 of the Immigration and Refugee Protection Regulations, which sets the legal standard for a “complete” application (forms, required documents, information, signatures, and fees). If an application is missing required elements, IRCC can treat it as incomplete and return it. Official regulation text is here: Immigration and Refugee Protection Regulations: section 10.
At the R10 stage, IRCC is not deciding whether your relationship is genuine or whether you are eligible. The focus is basic completeness: did you submit what the checklist and guide require on the day you applied?
Why “not processed” happens: returned before AOR
When an online spousal sponsorship file passes the R10 check, IRCC can issue an AOR and the application enters processing. IRCC uses “R10 passed” language in its internal/operational definitions of an AOR for permanent residence files: IRCC: terms and definitions (AOR / R10 passed).
If the file fails R10, you may be returned to “start again” with corrections. That can cost weeks or months, especially if you discover missing documents late or you need new civil documents or translations.
What IRCC expects you to follow (the guide and the checklist)
For spouse/common-law partner sponsorship, IRCC expects applicants to follow the official instruction guide and the correct checklist for their scenario. Start with these official sources:
- IRCC: sponsor your spouse, partner or dependent child
- IRCC Guide IMM 5289 (complete guide)
- IRCC Document Checklist IMM 5533 (spouse, including dependent children)
- IRCC: sponsoring your spouse, partner or dependent child (how to apply and avoid mistakes)

Common R10 mistakes that cause inland spousal sponsorship returns
Based on how IRCC frames completeness requirements (guide + checklist), these are the issues that most often trigger an R10 failure:
- Missing signatures (digital or hand-signed where required): even one missing signature can make an application incomplete.
- Missing required checklist items: IRCC expects the checklist to be followed exactly and expects required documents to be included at submission (not “later”).
- Using the wrong class or pathway: sponsoring inside Canada vs outside Canada can affect which process applies and what you must submit. IRCC explains the class choice in Guide IMM 5289. IMM 5289 (choose the class)
- Missing fee receipts or incomplete fee payment: fee proof is part of a complete submission.
- Missing translations: documents not in English or French must be translated following IRCC rules (and often include an affidavit/certified copy requirements depending on the situation).
- Uploading unclear scans: unreadable civil documents, passports, or proof of relationship can create completeness issues if IRCC cannot confirm required items are present.
A practical “before you submit” checklist (to reduce R10 risk)
- Download forms and checklists fresh on the day you finalize your application (avoid outdated versions). Use IRCC’s form pages, not saved copies.
- Match the checklist line-by-line and create a simple folder structure that mirrors it (identity, relationship proof, civil docs, fees, etc.).
- Confirm signatures twice (sponsor and principal applicant where required).
- Confirm fees and receipts are included and readable.
- Do a final “readability audit” (open every PDF/image you uploaded and confirm it’s clear, complete, and the right document).
FAQ
What does “R10” mean in spousal sponsorship?

What is the best official resource to avoid completeness mistakes?
Use IRCC’s complete guide (IMM 5289) and the correct document checklist (IMM 5533) for spouse/common-law partner applications. IMM 5289 and IMM 5533.
Where do I start if I’m not sure whether to apply inland or outland?
IRCC explains the difference and how to choose the correct class in the official guide. IMM 5289 (class of application).
Reality check
The R10 completeness check is one of the most avoidable reasons couples lose time in spousal sponsorship. A returned application can delay work authorization planning, document timelines, and family stability. If your situation is complex (previous marriages, country-specific civil document issues, missing documents, or unusual relationship timelines), the risk of an incomplete submission is higher. Before submitting, rely on IRCC’s guide and checklist, and treat completeness as a “pass/fail” step that must be handled carefully.
