You can sponsor her (I did for my partner). But my partner had 500k in his own account for 2 months.
🔍 search the group for “sponsor” and see what people’s experience has been recently.
I remember reading some people from London got sponsored by their parents. Which embassy would you apply from? London is one embassy which is more lenient regarding how long the 500k is in your account for.
I would still ensure she has 500k in her own account (to prove she can support herself), even if it’s only in there for 1-2 statements. And then provide her with a sponsor letter and your bank statements for her application where you also have minimum 500k balance
