Can you clarify, “support for my family (wife, kids) costs me ~60K” — is this some sort of child support + alimony? I assume no since you didn’t say ‘ex-wife’. It seems like $75K/year for mom+wife+kids could be lowered significantly; mom=’free daycare’ so wife can get p/t job (though they are probably thousands of miles apart, and wife does not have work visa?). You should be able to cut those costs considerably anyway.
