I am a senior associate in the Immigration Department. I specialise in family immigration matters, including complex applications under the immigration rules, human rights claims and European cases.

I trained at Freshfields, where I qualified into the corporate department. I later switched to the immigration field and worked for many years at Wesley Gryk Solicitors, a niche immigration firm.

I have also worked as a senior lawyer in the personal immigration team at Kingsley Napley LLP and as an immigration PSL at LexisNexis. Since 2016 I have co-convened the Immigration Law Practitioners’ Association Family and Personal migration working group.


  • I represented a client in her successful appeal against the refusal of her human rights application.

    She had been granted leave to remain as a dependent and made a human rights application in her own right after her marriage had broken down. Her circumstances were unusual and compassionate. The appeal was allowed on the basis of her private life under Article 8 of the European Convention on Human Rights.

  • I advised a Commonwealth national who had lived lawfully in the UK since the 1980s but was now encountering problems as his indefinite leave was endorsed in an expired passport.

    We discussed whether he would apply for a “no time limit” biometric residence permit (BRP) and the option of applying under the Windrush scheme. He successfully made a Windrush application and was issued a BRP without having to pay any application fees.

  • I acted for a woman who had been refused a business visit visa on the grounds of deception. We challenged the decision in a judicial review arguing that the refusal was irrational.

    The Home Office responded by offering to withdraw the refusal and look at the matter again. Her visa was issued and she was able to visit in April 2019.

  • I have provided advice to a couple on the financial requirement that applies to partner applications under Appendix FM
  • I advise European nationals and their family members about Brexit and the EU Settlement Scheme
  • I represented a client in her (successful) appeal against the refusal of her human rights application
  • I engage with the Home Office on family policy issues, including adoption issues and the “sole responsibility” rule
  • I give advice on the absence and good character requirements for naturalisation applications
