Dear doctors! I am so much worried now a days… Kindly help me out if u have some piece of suggestion for me… I have some questions regarding medical carrier in Australia… I am living in saudia now a days with my husband. I have done my mbbs from Pakistan. In 2017… I am currently preparing for mrcp part 1 Jan diet… I have also cleared fcps part1 exam of Pakistan which is an entry exam for residency training in pakistan but due to some personal issue I am not going in pakistan right now for starting training…
My husband is an electrical engineer and having a good job here with handsom salary… He wants to apply for immigration to Australia… Now I have some questions
1 - - should I go back to Pakistan for training and after specialization I should apply for job in Australia?
2----is this so much difficult to get entry into Australian training if u also have children?
3----- if I move to Australia should I eventually stop my carrier???
Kindly if any lady with same circumstances reply me… Thank u
