LOC vs EP/S-pass

You can’t apply LTVP for you when your spouse is working overseas.

Cause before you apply LTVP, your spouse need to submit her last 3yrars Income tax return in Singapore and last 12 months deposits in CPF account. Only one way you can come here either as a visiting visa or get a  job then come with work visa.

Your spouse can apply LTVP for you  only after staying here min 3 years (this part please check with ICA). Below link is for your reference:

I heard that it is possible to get an LTVP when moving back to Singapore together with a SG citizen spouse - but only if she has sufficient income to support both of you. Ask ICA or your nearest SG embassy for details - it's not a common constellation and I don't know how, in such cases, they handle the 3 yrs IRAS report rule Surya refers to above.
There is no possibility to get an LTVP as a dependent without the person you depend on.

Cheers for the response.

Have gotten in touch with ICA and they have confirmed that it is possible to apply for the LTVP without 3 years' prior Singapore Tax Returns as long as we can furnish the application with applicable tax information from the relevant authorities of the overseas country.

True, it’s not necessarily required. ICA has softened its stand on this. In fact if a Singaporean doesn’t stay here nor paying any income tax (but has a property) can apply LTVP for his/her spouse, who is a foreigner. But, during approval process, they look into other yardsticks which they don’t disclose. Good luck
