Open Borders is a free immigration guide written by an immigration attorney. Answer plain-language questions about your situation and read authored information about the paths that may apply to you — family-based green cards, asylum, cancellation of removal, waivers, TPS, DACA, U and T visas, naturalization and more. No account, no ads, no tracking. GUIDED REVIEW • Start from the beginning, or use Quick Start to record the facts you already know. • The guide asks only for the context it needs and explains each answer in plain language. • Focused tools for Family-Based Options and Removal Relief when you want one topic at a time. • Case Snapshot shows your progress; Case Notes collects what matters. Export your notes as a PDF and share them with an attorney. • Your answers stay on your device unless you choose to share them. IMMIGRATION COURT INSIGHTS • How every sitting immigration judge and court has decided cases since 2021, from the government's own records: asylum grant rates, bond outcomes, relief by type, time to decision, and appeals. • A map of who appointed each state's judges, the Board of Immigration Appeals roster, and notable numbers across the system. • Past decisions, not predictions — and never a tool for choosing a judge. PROCESSING TIMES • Current USCIS processing times by form and office, with a personalized estimate for a pending case. • The State Department's Visa Bulletin, read as a waiting line: which filing dates are being decided now, and how far the line moved in the last year. • Department of Labor queues for employment-based cases. ALERTS AND NEWS • Firm-authored alerts when a rule, fee or court decision changes what you should do — with who is affected and what to do next. • A curated archive of reporting, broadcasts, video, audio, public records and commentary on immigration law, civil rights and Montana's immigration history. • An emergency guide for families after an ICE detention in Montana. WHEN YOU WANT A LAWYER • Schedule a phone or video consultation with the attorney who wrote the guide, from inside the app. • Clear flat fees, with monthly payment options, for the services the firm offers. • Client reviews and the firm's story, in the app. ENGLISH AND SPANISH • The guide, the tools and the alerts are available in both languages. • Read Aloud, text scaling and other accessibility support. MADE FOR EVERY SCREEN • iPhone, including the iPhone Duo: a one-handed layout on the cover display and a full two-column layout when it is open. • iPad, with a sidebar and tab bar in every orientation. ABOUT THE AUTHOR Open Borders is written and maintained by Shahid Haque, founder of Border Crossing Law Firm and a former law professor, who has represented thousands of people in the U.S. immigration system since 2008.

Flange bolting data, instantly, offline. Flange Bolt Chart puts the ASME reference tables a pipefitter actually needs into one fast, native app — and it works with no signal at all. LOOK IT UP IN SECONDS Type "6 300 wn" and go straight to the answer. Search understands nominal pipe size, pressure class, flange type and facing in any order, so you are not tapping through four dropdowns while standing on a scaffold. WHAT'S INSIDE • Flange bolting — number of bolts, bolt diameter, wrench size (standard and heavy), bolt hole diameter, drift pin diameter and stud bolt length • Stud bolt length calculator — the full ASME B16.5 equation with every component editable, so you can see exactly where the number comes from • Flange dimensions — outside diameter, bolt circle, hub diameter, thickness • Gaskets — flat ring, full face, spiral wound and ring joint • Pipe — look up by schedule, or work backwards from a wall thickness • Bolt threads — UNC and 8UN, with pitch, minor diameter and tensile stress area • Line blanks and butterfly valve bolting • Torque values and tightening patterns SEE THE JOINT A live bolt-circle diagram draws the actual flange face — the right number of holes, in the right places — and animates the star tightening sequence pass by pass. Pinch to zoom, hand the phone to the crew. BUILT FOR THE FIELD • Completely offline. Every table ships inside the app; nothing is fetched. • Large, high-contrast values you can read with a wrench still in your hand. • Imperial and metric throughout, switchable everywhere at once. • Every value cites the standard it came from. JOB SHEETS Group the lookups for a tie-in into a named job, then export the whole thing as one clean PDF for the crew or the materials list. Reference data is drawn from ASME B16.5, B16.47, B16.20, B16.21, B16.48, B36.10M, B1.1 and PCC-1. All values are guidelines based on published standards and theoretical conditions. Always follow the specifications provided by your client and the equipment manufacturer. PRO SUBSCRIPTION Pro Yearly — one year of Pro, $48.00 in the US App Store, local pricing elsewhere.
