the only conceivable reflection that such determination might have on you, is that you really, really want to become a solicitor, more so than a lot of people! so stick to it and something will come up, maybe even when you least expect it. In relation to qualifying in the UK....i still think its no harm applying and seeing what happens (that was my alternative). They have this huge concept of "vacation schemes" (their alt to internships) which play a huge role in people obtaining TCs further down the line, with the firm that they did the vac scheme with....apparantly, easter is when people usually apply for those, and august when people apply for TCs. You never know, you might get an offer and might actually like the firm and living in the UK and might not want to move back home, and if you do, that guy you talked to is just one example of someone who couldnt find a job after qualifying in the UK, and i would doubt that it is any sort of reasonable reflection on employment prospects of people with UK qualifications.
is there any chance of the firm with which you are paraligalling offering you a TC?
