Yes, someone may help you in filing your entry. However, you are encouraged to complete the entry form yourself, without a “visa consultant,” “visa agent,” or other facilitator who offers to help.  Some agents may claim that they can get special attention for your lottery registration if you pay them to handle it. Others may claim that your chances of being selected will be increased if the entry is filed on your behalf by someone resident in the U.S. There are no truths in these claims. There may be nothing wrong in paying an agent to help you complete the registration according to instructions. Yet, that is the only help they can offer; but no more.
