This is correct. Tenants can file the TM 30 on their own.
Section 4 of the Immigration Act:
Section 38 of the Immigration Act:
According to Section 4, whoever is the "chief possessor" of the house (in Section 38 called the dwelling place) is the householder.
If a tenant is the chief possessor, the tenant is the householder.
If the owner is the chief possessor, the owner is the householder.
If another person, natural or juristic, is the chief possessor, that other person is the householder.
In my opinion, with a rented property it is best for the householder, ie the tenant, to submit the TM.30 notification. It is he, the tenant, who has the sole authority to decide who resides in the dwelling and it is he who knows when a foreigner, ie himself or an invited guest, arrives and whether this arrival makes a TM.30 notification necessary.
In fact, as the owner I would write into the lease contract that the tenant is responsible for compliance with any and all immigration requirements and that I will provide the necessary documents for that purpose.
