Rescinding its more than 13-year-old policy, the US Citizenship and Immigration Services (USCIS) said that the burden of proof in establishing eligibility is, at all times, on the petitioner.
USCIS said the previous memorandum of April 23, 2004 appeared to place this burden on this federal agency.
"This memorandum makes it clear that the burden of proof remains on the petitioner, even where an extension of non-immigrant status is sought," USCIS said in its latest memorandum issued on October 23.
Under the previous policy, if a person was once found to be eligible for a work visa initially, they would usually be considered for extension of their visa.
Very good information
