Start with the resume word document properties, check for the name of theauthor, if it isn’t candidates’ name then something is fishy
Look out for typical resume formats and responses mentioned above
Check their online presence, primarily LinkedIn (this might not work all the time). Most of the candidates with fake resumes doesn't have any online presence (Facebook, Linked, Twitter, Instagram)
Ask the names of the project managers they are currently working for and look up their names on LinkedIn (This holds good for OPT candidates but not for the recent H1B candidates)
Ask for the copy of highest degree
Ask for candidate's 1-797 copy (when first applied) and make a note of the receipt number. Cross check I-797 status using https://egov.uscis.gov/casestatus/landing.do. Plug in the receipt number to find the date of approval and is fool proof since the information obtained is directly from USCIS.
VerifyI-94 information using https://i94.cbp.dhs.gov/I94/request.html. You need to get the passport copy and the consent from the candidate . This is again fool proof since the information obtained is directly from Department of Homeland Security.
Verify Divers License or any photo ID
Finally, cross check dates from each document.
Note: These folks are capable of forging any document. So, when you look at the documents focus on Names, Date of Birth, and Visa Approval Dates/Expiry Dates. Zoom in to the area and make sure they are not tampered. Look for changes in the document background (color/texture/white box), change in font style/size.
Often, it is hard to get the documents form the candidates. In that case, the only option left out is to ask the consultant to prove their experience/authenticity
