Cheapest comp sci bachelor online degree?

As most desirable countries don't give too much on work experience alone, I'm looking to take the plunge at age 30 and get an internationally recognized online comp sci bachelor.

I finished school at 10th grade because I had to go to an unsafe ghetto school, so I don't have anything equivalent to a highschool diploma and I'm currently working as an iOS dev.

Open University in the UK seems to be fairly recognized, however the computing and IT degree doesn't look that great and I'm not too sure if it'd be considered equal to comp sci by the bureaucrats who process visas.

I'm thinking of emigrating to Canada, the US (extremely unlikely with the H1B situation), Hong Kong or Singapore in the future in case anyone has some personal experience with either getting a visa based on work experience alone or with an online degree.
