English requirement documents for spouse visa

Hi,

I am applying for my wife's dependent visa - ie., 'Apply to enter the UK as a partner' . She was in UK earlier for 3 years and went back due to maternity and I am bringing my wife and sone back to UK to provide the background (and I have ILR in UK).

My wife is having a degree that was thought in English in India, however the certificate doesn't specifies the medium of instruction as English. I have a question regarding the English language requirement, hope you can assist/guide me.

For the below questions, I answered as below and ......


Do you have a degree that was taught in English?
>Yes
Country your degree was taught in
>India
Does your degree meet the English language requirement for this visa?
>Yes
What will you use to prove your degree taught in English?
>Degree Certificate

and ...... at the 'documents' section, I see the below 2 documents as required.
i am confused around these documents and need some clarify.

For document a) please can you guide me if ECCTIS letter is mandatory for my wife based on her degree certificate ? Or have I answered wrongly
If I need ECCTIS letter, can you guide me how do I get this in India ?

for document b) providing my wife's degree certificate is sufficient I believe ?

a) Ecctis letter that confirms the qualification meets or exceeds the
recognised standard of a Bachelor's or Masters degree or PhD in
the UK AND confirm the level of English to which the degree was taught or researched

b) The degree certificate for xxxxxxx to prove the level of English language required

She needs ecctis if using a foreign degree to meet the English requirement.

Thanks for your response.
I have 2 more questions. Hope you can help me.
1. Related to 'Engligh language requirement'. Can my wife take B1 test in India instead of going through 'ECCTIS letter' ? If so, can you please advise which is the appropriate test to be taken.
I found the below from website, however, not sure which exact test to be taken (because each provider has test name etc., ) would appreciate your guidance.

2. UK Accommodation:
I am currently staying in a private rent and dont have a rental agreement or no bills are on my name (its a privately rented place). As a mandatory document for my Son's visa application, its asking me to provide ' rental agreement' Please can you advise what I can do in this scenario?

Dear CR001, please can you provide your valuable feedback on my query
