I have appled for a PR visa under spouse sponsorship category from london. But my visa in london expired within the period. so, i asked them to change my file to my home country. They asked me to allow 8 weeks to arrive to local visa office. this is 15th week. no one contacted me. local visa office and london visa ofiice both couldn't find my file. London visa office says:'We sent your file to your local visa office. Pls contact them'. Local visa office says:'We did not receive any file from UK'. Online status (in UK) appears as 'Withdrawn' from the date of transfer. I am totally upset. What happened to my file? What do I want to do next? How can I track it?
