they may say 5 years, but if they get no other responses which is better some one with 0 years experience or someone with 2.

5 years appears to be a general period put on nearly every job, have even seen it used on trainee jobs for school leavers. you are over 5 years old, you have more than five years experience of life so you qualify unless they say 5 years relevant experience.

You have another plus in your favour, you are here, so no problems of you not meeting visa requirements.
