Approach Your Immigration Goal Confidently

Immigration laws in the U.S. are constantly subject to revision. When you are applying for a green card, asylum, a work visa or trying to bring your family member to live here, you may have many concerns about whether you are completing the right documents and how much detail you should provide. You may be worrying about your privacy, but what if you do not have enough evidence of your relationship? Just what does the U.S. need to know about you and your circumstances? How long is this going to take?

Our immigration team here at O’Neil Hauser Mansfield, P.C., understands how confusing just about every part of the immigration process can be. Our lawyers and professional staff can help you confidently take the right steps toward achieving your goals. We will answer your questions, guide you with legal counsel and represent you at administrative hearings when necessary.

The pool of qualified local or national employees in certain fields of business can be finite. Sometimes, the ideal person for the position is from another country, but you have no experience sponsoring a foreign worker. Can your business afford the costs and responsibilities of hiring an immigrant? Where do you start? Do you really need an immigration lawyer alongside you to complete the process?

When your business plan includes hiring an employee or multiple employees who will need work visas, contact O’Neil Hauser Mansfield, P.C., in Boston for experienced legal help. We have insight to help you anticipate the potential pitfalls of hiring non-native employees. You can try to do it yourself with the information you find on the internet, but the process is more efficient when you work with a knowledgeable lawyer.
