The 25-year-old, identified as Maya, was found shot in the head at her rented property in Defence, Lahore, on Monday, Dawn.com reported.
Police have said they are looking for two suspects.
Police Superintendent Sayyed Ali said: “We are also after two suspects and will share further details at a later stage.”
Local reports suggest two men were competing for the woman’s hand in marriage.
Before her death she had told her uncle that two of her friends had been threatening and harassing her, according to the Independent Urdu.
He then received a phone call from her father at around 2pm on Monday saying she had been killed.
The woman arrived in Pakistan from the UK two months ago.
She was living with a friend in the property but police said she had no useful information.
