I want my Colombian partener to come and live with me in the UK, we're not married but she is pregnant with my child, I need here here ASAP as I'm 100% she's the one. 

Any chance she can come here before applying for long term visa/citizenship? As I know that Colombians no longer need Visa to come as a tourist. I work full time on good pay, I'm English with an English passport. How hard is the government going to make it so my partner carrying a child from someone English can live with me so we can start our family?
