Hi,
I would like to ask if it is feasible to acquire a UK Working Visa even if you do not have an employer yet. I am a Filipino IT professional, specializing in Software QA/Software Testing. I am very interested in working in UK and have seen a lot of job postings related to my specialization. However, my big dilemma is most of the agencies/companies that reply to me require an existing UK working visa.
Can I apply on my own even without sponsorship?

Thanks.
