@milktea13 during lodging, other options na available for evidence of relationship aside sa namention mo are:
health insurance
lease/tenancy agreement
financial statements
telephone bill, utilities account
asset ownership - joint
in our case nagsubmit kami ng screenshot ng account statement ng stocks namin (from colfinancial) and tenancy agreement namin dito sa sg as additional evidence (both documents have our names in it). If you have insurance and bills na nakapangalan sa inyong 2, pwede rin yun. hope this helps
