O-1 EB-1A EB-2 NIW Recommendation letters Petition

About this document

An independent recommendation letter for an EB-2 NIW petition, written to USCIS by a field expert who says they have not worked with the applicant. It summarizes the applicant's research in bioprocessing, especially biomass conversion from Eastern redcedar and switchgrass to biofuels and biobutanol, and frames those works as outstanding. The letter highlights process improvements, production results, and citation impact as support for the petition.

Key points

  • The recommender states no prior collaboration with the applicant and bases the opinion on independent review and published research.
  • The letter relies on an ASABE presentation about pretreating Eastern redcedar into fermentable sugars for biofuels and bioproducts.
  • That presentation is described as cutting water and chemical use by about half and temperature by about 20% while keeping high sugar yield.
  • A published study on size reduction reports ethanol production from 2.5 mm crumbled redcedar comparable to 0.5 mm ground wood, with 68-93% energy savings.
  • A butanol process from Eastern redcedar is described as including pretreatment, enzymatic hydrolysis, detoxification, and anaerobic fermentation.
  • The letter says this work suggests 315 million gallons of butanol from 11.5 million dry metric tons of redcedar biomass in Oklahoma.
  • A switchgrass study is said to remove inhibitors with activated carbon and produce 11 g/L butanol; it is cited more than 40 times in four years.
