The United States Citizenship and Immigration Services (USCIS) provides free information and resources to guide applicants in their immigration processes and procedures.
The USCIS warns about fraud and scams related to obtaining visas or immigration status in the United States, also provides information to prevent migrants from going through situations of this type.
Some of the more common immigration scams include false information about TPS re-registrations, there have also been email scams related to the I-9 form.
Remember that when consulting information on procedures it is necessary to verify that the content cites official information from the USCIS and the United States Government. In addition, when consulting directly in government pages, you must make sure that the address of the site has the ending .gov.
Remember that forms for any type of immigration procedure are available for free on the USCIS website, so any website that offers forms for a fee is a fraud.
Another recurring scam is alleged payments by email or phone, however, the USCIS does not support transfers online or through financial services. Some fees can be paid online, only through your USCIS account at myaccount.uscis.gov or at pay.gov. Consult the official information on the payment of fees in immigration processes: https://www.uscis.gov/forms/filing-fees
Scammers also seek to deceive potential visa applicants, through visa lotteries, which are not administered by the USCIS, but by the State Department. The only visa lottery program is Diversity Immigrant Visa (DV) and it is free. Any information on this program that talks about "fees" is a hoax. Learn more about this program on the official site of the Department of State about this program: https://travel.state.gov/content/travel/en/us-visas/immigrate/diversity-visa-program-entry.html
On the other hand, there are also scams aimed at international students, so we recommend you to know which are the accredited universities or colleges in the United States to receive foreign students: http://ope.ed.gov/accreditation
