I got married to this guy in pakistan (his country) and later after a month we came to London. we thought I should file petition I-130 for him while he is in London and get interveiwed in London. So we registered our marriage again in London (assuming this filing would need marriage registered in London.)
But now we have decided to submit our Pakistani marriage certificate with i-130 petition as we have enough evidence for that. does this London marriage affect our application/petition at any stage.
