While on the hunt for prospective employment, I noted some positions that I liked a lot, but, unfortunately, they were located outside of the country I live in (and hold citizenship of) and did not explicitly mention visa sponsorship packages. Some of them had relocation help as part of the benefits provided, and some had neither visa nor relocation packages mentioned.
I still want to apply to these positions, but I want to make it clear to prevent any confusion that I will likely require additional help in the process (even if it as much as having a job offer in a form I could present during the visa interview).
I understand that the cost of visa sponsorship is quite high, and thus am wondering how willing the average company would be to agree to such a request for other concessions, and what concessions might increase my chances.
So, to summarize the question - how reasonable would such a request be from the company's point of view, provided I fit the requirements mentioned in the job posting?
Edit: the country I am from is Russia, and the countries which I'm considering include the UK, France, Germany and Australia.
Edit 2: As it is apparently unclear what I am asking, here's an even more abridged version of the question: how does a company determine whether a request for visa sponsorship, which is not normally offered by that company, should be granted and what does it take into consideration?
