Hi,

No country is easy to aquire a Residency position. All countries require doctors and all of them have shortage, what you should think is where can you see yourself after 10–15yrs if you think USA is better for you go for it, if you think UK is better option go for it. Anywhere you go, you will have to give a huge dedication to get yourself a Residency position may it be - USA/UK/AUSTRALIA.

PLAB is easy, yes PLAB can be considered easy to other entrance exams but there are limited training positions for British students itself leave apart imgs, even if you get one the training is apx 6–8 yrs long ,in near future you can face VISA issues UK ain't giving citizenship easily to anyone.

Thinking about AUSTRALIA, the AMC exam is difficult and the situation here is again the same like UK, the img doctors are rising than the Australian doctors, who would like to see their country filled with foreign doctors and minimum national doctors, but again this shouldn't stop you because you can be the exception if you want to all you need is determination and hardwork.

Thinking about USA, yes the process is tiring 4 exams, so much of expenses no guarantee of getting a interview , few spots in fancy branches for img's, but this isn't what should be looking for ,look if you like usa, do you like their education, their healthcare system can you live your life in that country if you can its a great option but if can't you got a lot of time spend it on thinking and Making the right decision .

Finally considering a option to make on my opinion, I would suggest w.r.t easy to get medical license  -

USA>UK>AUSTRALIA

Hope this helps.

Good luck.
