Visa for wife to join me in UK

[ssbib]

There is only one test centre in manila that's approved for the tb test for the spouse visa.

Ielts has to be minimum life skills A1 level at an approved centre. There is a list of current approved test centres on the UKVI website.

If your wife has good English she should try and get level B1 as that'd required for ILR and means she won't need to get A2 for FLR as well

She hasn't good English so I'll get her to go for the B1. Is that the highest level there is? I thought I remembered somebody say to go for a certain level so that she doesn't have to re-test for citizenship in the future. Is that B1 also or is there one that is higher?

How can I find what he approved test centre for TB is in Manila? Does anyone have that information handy? Thanks.
