Hey I am an Indian passport holder and based on my research I think we get two options : 1) is to apply from spanish embassy at country of origin or 2)directly from spain but there wasn’t much extrapolation on this bit specific to my context :/

Ps: they are giving me a freelancer contract

Can I apply for it if I am already in Madrid and currently on a work search visa but have an offer letter for remote work from a firm in Copenhagen? My firm is flexible to change my address from Spain to my country of origin if that would help better my case as I need to show 3 months of work experience with the firm prior to applying
