Marcia Longdon

Marcia joined as a partner in the Immigration team in January 2014. She has practised in the area of immigration, nationality and European law since 1998. She has had a long career in the field of immigration and is incredibly passionate about this area of law.  She has won a number of challenges against the Home Office regarding complex cases, which have resulted in discretionary leave for her clients.

She has a collaborative approach with the Home Office and government officials and is often invited to participate in consultations and round table discussions on changes to UK and European immigration. Whilst some of these meetings are conducted under Chatham House rules her input to these discussions are well received and often incorporated into material produced by the government.

She assists corporate clients in reviewing their work force and planning ahead, particularly when considering mergers or acquisitions. Marcia also leads our internal global offering with the 76 law firms around the world, frequently coordinating with international partner firms to assist the client and their family.

Marcia’s experience spans nearly 20 years in the industry. She has become a leading expert on corporate immigration covering mergers and acquisitions. She is incredibly knowledgeable with HR policy, compliance and risk analysis; reporting and audit planning; high touch service planning for executives and VIP’s; business traveller compliance; cost and budgeting as well as global project planning. In her early career she represented clients as an advocate before immigration judges and prepared cases for judicial review. 

Marcia has excellent industry knowledge in the following: oil and gas, banking and finance, telecommunications, insurance and pharmaceutical industries. Marcia also provides training to HR professionals and practitioners on compliance and reporting. She is a popular speaker at internal as well as external immigration events and conferences.

Marcia will also often assist clients who may have had their applications refused and is often recommended to give a second opinion to clients looking to find an alternative solution. 

Recent work

• Assisting a nuclear power organisation employing specialist nuclear technicians to bring the necessary specialist migrants to the UK. The nuclear specialists have now been able to come to the UK as Tier 2 migrants in order to fulfil their contractual obligations.
• Advising a client whose ultimate parent company was acquired by a Japanese company, retain their Sponsor Licence for Tier 2 migrants. Representations were submitted to the Home Office explaining that there had been no changes to the immediate employer of the sponsored migrants and as such it would be disproportionate to require a new Sponsor Licence to be submitted.  It is a relief to note that the Immigration guidance has since been amended to confirm that a new licence is not required in these circumstances.
• Advising a T4 student who had a criminal conviction to obtain a visa to return to the UK to undertake his studies. The Immigration Rules state that applications should normally be refused if the applicant obtained the said conviction within 12 months preceding the application. We argued that this was a one off incident and out of character and the UKVI agreed with us and approved the application. The individual was allowed to the UK and commence a new degree course. 
• Well-known theatre production – advised the parents of a child actor who wanted to remain in the UK as their chaperone. However, the parent had over stayed their initial permission because they argued that they didn’t want to leave their 7 year old child in the UK. Although, the production company had chaperones for the children the parent was adamant that they wanted to remain throughout the production. We advised the parent to return to their country of origin and managed to successfully convince the UKVI to allow the parent to return to the UK, despite the previous overstaying and in addition to allow them to stay until the child’s part was completed, which was approximately 12 months.
