Consistent with precedent case decisions and existing regulatory requirements, further deployment must continue to meet all applicable eligibility requirements within the framework of the initial bases of eligibility,[44] including the same new commercial enterprise.[45] The further deployment does not need to remain with the same (or any) job creating entity or in a targeted employment area (TEA).

Corporate, partnership, or any other entity in any form which has filed in any country or subdivision thereof any return described in this list, and personal tax returns, including income, franchise, property (whether real, personal, intangible), or any other tax returns of any kind filed within 5 years, with any taxing jurisdiction in or outside the United States by or on behalf of the immigrant investor;

Certified copies of any judgments or evidence of all pending governmental civil or criminal actions, governmental administrative proceedings, and any private civil actions (pending or otherwise) involving monetary judgments against the immigrant investor from any court in or outside the United States within the past 15 years.[56]

Personal tax returns, including income, franchise, property (whether real, personal, or intangible), or any other tax returns of any kind, filed during the past 7 years (or another period to be determined by the Secretary to ensure that the investment is obtained from a lawful source of funds) with any taxing jurisdiction within or outside the United States by or on behalf of the investor;

For petitions filed on or after March 15, 2022, USCIS designations of TEAs are valid for 2 years from the date of investment for standalone investors or 2 years from the date a regional center properly files the Form I-956F for regional center investors and may be renewed for one or more 2-year periods.[76] An immigrant investor who has invested the amount of capital required for a TEA during an approved designation does not have to increase their investment if the designation expires.[77]

Jobs that are intermittent, temporary, seasonal, or transient in nature do not qualify as permanent full-time jobs. However, jobs that are expected to last at least 2 years are generally not considered intermittent, temporary, seasonal, or transient in nature.

For purposes of determining whether or not the troubled business has been in existence for 2 years, USCIS deems the successors-in-interest to the troubled business to have been in existence for the same period of time as the business they succeeded.[117]

For petitions filed on or after May 15, 2022, Congress enacted certain limits on how jobs created by construction activity lasting less than 2 years can count towards estimated indirect and direct jobs.[123]

A copy of a comprehensive business plan showing that, due to the nature and projected size of the new commercial enterprise, the need for not fewer than 10 qualifying employees will result within the next 2 years and the approximate dates employees will be hired.[127]

The 2-year period[128] is deemed to begin 6 months after adjudication of Form I-526. The business plan filed with the immigrant petition should reasonably demonstrate that the requisite number of jobs will be created by the end of this 2-year period.

Designated regional centers must file a Supplement to Form I-924 (Form I-924A) annually that demonstrates continued eligibility for designation as a regional center in the EB-5 Program.[12] The regional center must file the form within 90 days of the end of the fiscal year (between October 1 and December 29). The Form I-924A instructions specifically list required information that must be submitted.[13]

Guanine (G)-rich sequences of single-stranded DNA and RNA can fold into stable, intra- or intermolecular secondary structures called G-quadruplexes (dG4s and rG4s). These nucleic acid structure scaffolds are composed of stacks of G-quartets and can be further stabilized in the presence of monovalent ions, preferentially K+ or Na+ but not Li+1,2,3. Earlier findings have shown that G4s play important roles in various cellular events, including but not limited to DNA replication, DNA damage repair, transcription, translation, RNA metabolism and epigenetic remodeling3,4,5,6,7,8,9. The ability to regulate fundamental biological processes, as well as their chemically interesting structures, makes G4s promising targets for potential cancer, antimicrobial and antiviral treatments10,11,12,13,14,15,16,17,18,19. With the mounting interests in the biological role of G4s, more structure-specific, sensitive and low-cytotoxicity tools are needed to not only differentiate between G4s and duplexes, but also among different subtypes of G4s, to allow gene/transcript control and manipulation by selective targeting of specific G4 structure in any gene/transcript of interest.

As we have successfully showcased the validity of rG4-SELEX using different rG4 targets in our proof-of-concept studies30,31, we believe this method can be a novel strategy to create highly specific, noncytotoxic and nuclease-resistant rG4-targeting probes. The unique tertiary interaction between each l-aptamer (l-Apt.) and d-RNA G4 can potentially achieve an unprecedented specificity in G4 targeting, i.e., distinguishing an individual rG4 from other RNA structure motifs such as hairpins and stem loops, or even between dG4s and rG4s30. In terms of potential biological applications, we have demonstrated that these spiegelmers can interfere with the binding of the target rG4s with biologically relevant peptides or proteins30,31, with a half-maximal inhibitory concentration (IC50) comparable to state-of-the-art small-molecule G4 ligands31, which may be used as a strategy for G4 targeting therapeutics. The nuclease-resistant nature of these rG4-targeting l-RNA aptamers also allows them to be promising probes for developing trackers of G4 folding and unfolding dynamics, or high-specificity vehicles for delivery in cells by coupling them with fluorophores or other moieties of interest, respectively. Besides that, these rG4-targeting l-RNA aptamers can also be employed as rG4 ligands to regulate rG4-mediated gene expression and RNA metabolism, as well as control of gene activity for diverse applications32. Recently, Tolnai et al. developed a sandwich detection assay based on two different speigelmers that bind to the C- and N- termini of cardiac troponin I, respectively, which suggests spiegelmers can be developed into highly sensitive and specific sensors for biopolymers33. A similar strategy may be designed for biosensing of rG4 using rG4-targeting spiegelmers.

Another crucial aspect of rG4-SELEX is the choice of rG4 target and label to use. Some of the factors to consider in choosing an rG4 to be targeted by the l-RNA aptamer that is selected during the procedure include its biological relevance, binding modes to other molecules, rG4 structural subtypes such as canonical versus noncanonical rG4, etc. The labeling of the rG4 target should also be carefully considered in terms of its intended purpose (selection or binding test), taking into consideration factors such as its physical size and excitation and emission wavelengths. For instance, for selection, a biotin label is commonly used for partitioning the bound and unbound aptamer candidates using streptavidin-coated magnetic beads, while for binding tests, fluorescein (FAM) and Cy5 labels are an example of labels with different sizes and emission wavelengths, etc. All oligonucleotides used are obtained commercially and dissolved in ultrapure nuclease-free water to desired concentrations.

rG4-SELEX consists of three major stages, namely (i) selection, involving positive selection to allow the binding of the randomized d-RNA library with biotinylated target, as well as the removal of nonspecific library sequences using negative selection with streptavidin-coated magnetic beads; (ii) partitioning, involving the separation of library sequences that bind to the target and those that do not bind to the target; and (iii) amplification, involving the amplification of the selected library sequences to generate sufficient amount for subsequent selections.

Aptamer sequences are ranked based on their frequency of appearance or abundance. Then, a few of these top-ranked candidates are selected for further analysis (five to ten candidates, depending on the number of clones sequenced). The structures of the selected aptamer candidates are determined using Mfold structural prediction server. Any sequence conservation and/or structural similarity across the selected aptamer candidates is noted at this point. As Mfold does not predict rG4 structure, the identification of rG4 motifs can be separately done using the QGRS, G4hunter and G4NN prediction tools89,90,91. Next, the binding of selected aptamer candidates to the target is tested using electrophoretic mobility shift assay (EMSA) or microscale thermophoresis (MST). Afterward, aptamer mutations such as truncation, substitution and base-pair covariation are done to identify the shortest possible aptamer construct that has similar binding affinity to the full-length aptamer.

Advisably, at least two different binding assays should be used to test, characterize and validate the binding of aptamers and their corresponding targets. In this protocol, we employ EMSA (option A) and MST (option B) to resolve the bindings between selected aptamer candidates and their targets.

Order a FAM-labeled d-RNA rG4 target and the l-RNA of the optimized aptamer candidate to confirm the binding repeating Step 110 with the l-RNA version of aptamer and natural chirality of the rG4 target (d-rG4).
