I am aware of the QLTS , LPC and solicitorship system and that generaly its is very very difficupt for foreign grads to find job after llm in UK. But if I am not wrong there are corporate law firm and inhouse jobs,howsomuchever rare, for foreign graduates who have done LLM in UK with postings in either in UK or European countries.

I want to know if there are cases where you have seen LLMs getting training contracts converted to jobs.. or inhouse opportunities , specially for LLMs from QMUL. Do QMUL LLMs really get jobs at all ?

Unless you are already an top-tier candidate in your jurisdiction that elite firms would enter a bidding war over, the answer is no, you will not get a job suited to a qualified lawyer. 

With the two-year post-study work visa returning, you may perhaps be selected for a paralegal role, but even for that your English language skills must be immaculate. If your IELTS score is less than 9 and you don't fluently speak any language in hot demand (think Mandarin, Japanese, Russian), you're out of luck.

thanks a lot Varz! will keep in mind.
