Does immigration at CW always require a copy of the landlord's ID and house registration for a 1-year visa extension?

The requirement for providing a copy of the landlord's ID and house registration when applying for a 1-year visa extension at CW immigration can vary. Some users report that these documents are consistently requested during their extensions, particularly for Non-O visas linked to marriage. However, others have successfully obtained extensions without these documents, citing that they only needed their TM30 receipt. It appears that the requesting of such documentation may depend on the discretion of the individual immigration officer, and if requested, applicants should comply with the documentation requirements.
