Sector Expertise

Our highly experienced US immigration lawyers offer specialist US immigration services to global businesses, entrepreneurs, investors and high-net worth private clients across all industries.

In an increasingly borderless world, the nature of business continues to shift to that of a multinational framework. A driving force for financial service firms’ geographic diversification has been the proliferation of corporate combination strategies such as mergers, acquisitions, strategic alliances and outsourcing. The new global market demands highly skilled, mobile professionals who are able to form strong relationships with international clientele and respond to geographic expansion within the financial services industry. Our experience servicing this sector shines particularly bright.
Medical device and pharmaceutical industries have consolidated on a global scale and the way medicine is practiced is becoming more standardized. Wireless technologies are being utilized in different parts of the world to improve health worldwide and medical technology companies are forming to respond to the need of an ever increasing surge in the demand for and opportunities in medical technology sector.
International travel, tourism, and hospitality are some of the largest sectors of employment globally. Facilitating the global transfer of talent for a sector of this magnitude is key to business development. Our firm is highly experienced in servicing this industry.
Suitably skilled staff in the manufacturing sector is crucial to the success of the US economy. According to published statistics, for every 1,000 immigrants living in a country, 46 manufacturing jobs are created or preserved that would otherwise not exist or have moved elsewhere. The need for managed solutions to effectively encourage this growth from a mobility perspective is real and more important than ever before.
Clients depend on a predictable, and reliable flow of skilled employees in this public-facing sector. Technology allows for quick communication, fast and coordinated transport, and efficient mass marketing, all of which have allowed globalization—especially globalized media—to take hold. Low marginal costs of media mean that reaching a wider market creates much larger profit margins for media companies. With today’s heavy flow of information, a strong workforce is key to success.
Globalization means an abundance of fashions sold by giant retailers who can update inventory, make transnational trade deals, and coordinate worldwide distribution of goods at the click of a computer. One effect of globalization is increased immigration from into the United States to compete with the global market. Our firm has vast experience in this market and can respond to the needs of this market with practical experience and intelligence.
For most major law firms and accounting practices, global expansion has been a necessary step in boosting profits. As financial markets and capital flows went global, clients went global and technology allowed more efficient worldwide communication, the legal services industry had to follow suit. Understanding the global needs of our clients in this sector and anticipating the next solution is integral to our service offering. Continuous mobility of staff to provide worldwide support is paramount to the future of the professional services industry.
Serving as immigration counsel in the area of entertainment, including television & motion pictures, requires specific knowledge regarding the immigration benefits available for professional actors, actresses, and essential support personnel. Our firm knows the time pressures that are common in this industry and have expertise in the practices and policies of US embassies necessary to facilitate the quick transfer of talent to the United States.
It is said that publishing’s future is about global brands. Companies can no longer be competitive unless they have a global, digital brand to attract market share and users. The world’s major publishing companies as well as other smaller yet still prominent publishing houses, have their hubs in New York and it is important to keep channels open for the transfer of talent from the far reaches of the world to maintain a competitive edge.
As the cornerstone for a good foundation supports its structure, we do the same for our clients in the construction sector. Global organizations are forming every day and they require a multinational labor force. Managing this workforce on a global scale involves expert strategy planning to ensure that global contracts are fulfilled.
An increasing number of goods, services and talent belong to global marketplaces, thus recruitment firms must be attuned to the forces that drive their clients abroad. The most successful global recruitment firms will be those that can utilize the same recruitment solutions anywhere in the world. Our firm has an understanding of this market and can use our expertise to facilitate the transfer of talented specialist recruitment specialists to the United States.
The effects of technological innovation on the global economic structure are creating immense transformations in the way companies and nations organize production, trade goods, invest capital, and develop new products and processes. Technology companies are transforming the world around us and the importance of hiring the right staff, from around the globe can make or break a business in this fast-paced industry.
