Okay so 6 months passed since medical exam still nothing till now what should I do should I let my sponsors to reach out to the immigration minister or should I wait after the elections or should I file a mandamus case ? Please anyone could tell me of their experience
Mandamus only makes sense if your application has far exceeded normal processing time (meaning exceeded by years). Yours hasn't so IMO this will be a complete waste of time and money and they won't consider it.
Once the election is over, your sponsor can try reaching out to their MP. But again, it doesn't look like your processing time has exceeded standard processing times so not sure the MP will be able to help at all. But your sponsor can certainly ask.
