Nothing out of the ordinary except FSIA will no doubt tell you to bring a tow bar. They only have bars for B737, B747, B757, B767, B777 and A330, A319.
Landing permits easy at all locations and again, with FSIA, they will want you to transmit the permit number by HF prior to entering their FIR. Your ops should give you the HF frequency.
Usual health precautions apply for these destinations.
