The visa paperwork rests largely in the hands of the company. If you are calling workers from abroad to work for your business, you need to prove to the state that there are no hands available in the United States to deal with similar job category. We have seen many software professionals who come from places like India and Japan, to work in the United States and it has been a period of growth for professionals and companies. But when it is not possible to prove that there is a shortage of manpower in the category in the US; it will be very difficult to get a worker visa for employees. Generally, if you are honest reason to call employees, it should however not pose a problem.
Many times, entrepreneurs get caught up in trouble with the state when their employees come to the children that they are not entitled. This is a serious offense and the US do not take it lightly when people try and settle illegally, especially where children are concerned. You as an employer can not be responsible for the actions of your employees, but it is the least you could do to have a thorough background check on you are offering to live in the country.
Especially since you are calling workers from countries that the United States is opposed to as far as political views go double check the background of each employee. You may not even realize it, but many people would go to great lengths to get into the country for illegal purposes. What about terrorism at its peak, you have to take responsibility for issuing the offer letter only after you are sure the person’s background. The wrong one can get into the country with your letter of offer, so some responsibilities lie in the hands of employers.
But fortunately, more often than not, you will not have much problem with the law when you invite people to work for you from other countries. The main responsibility may lie in helping the employee paperwork such as real estate deals, and school admissions if a person brings their children. In any case it is advisable to seek the assistance of a lawyer with the legal paperwork that the company may have to undertake.
