I tried posting this on the Africa forum but didn't get any responses...figured there are actually probably more people here with MPM experience now

Does anyone have any experience with international-international transfers at MPM? I will be flying in from JNB on a LAM flight, and then out to DOH on the QR flight. I'm assuming that I won't be able to interline my bags, but will I have to clear immigration to collect them?

Assuming I have to clear immigration, does Mozambique have a transit visa, or am I required to get a full visitor visa (I've found conflicting information online)?
