F1 Visa Interview Data Insights — What 6,867 Real Interviews Reveal
A live analytics dashboard from Mainaka's canonical dataset. Every chart on this page is computed from 60,381 normalized question-answer pairs across India's five U.S. consulates.
CHART 01Approval Rate by Consulate
The dataset's approval rate by consulate. The aggregate 90.4% rate is structurally higher than current State Department FY2025 figures because applicants who experience approvals are more likely to share their accounts publicly. See Methodology · Limitations for context.
Dataset approval rate by Indian U.S. consulate
Computed from 6,684 in-scope interviews (excluding 183 undecided). Hyderabad has the highest rate at 92.2%; Mumbai the lowest at 88.2%.
CHART 02Question Category Frequency by Consulate
The seven primary question categories from our taxonomy, with the percentage of interviews at each consulate where each category appeared at least once. This single matrix encodes the entire "consulate personality" pattern that drives our cornerstone articles.
What each consulate actually asks about
Each cell shows the percentage of interviews at that consulate where the question category appeared at least once. Darker cells = higher frequency.
CHART 03Top 10 Most-Asked Question Patterns
The single most-asked question across all 6,867 interviews is "Who is sponsoring you?" — appearing in 25.5% of interviews. This is followed by funding-related and university-rationale questions. Procedural questions (passport, fingerprints) are excluded.
Most-asked question patterns across all 5 consulates
Frequency = percentage of all interviews where the question pattern appeared at least once. Patterns are matched via a versioned regex library (12-38 patterns per question type).
CHART 04"Why This University?" — The Universal Refusal Trigger
The single most refusal-clustered question in the dataset, broken down by consulate. The gap between refused-cohort frequency and approved-cohort frequency is positive at every consulate, with Mumbai showing the largest gap (+14.8pp).
"Why this university?" question rate — approved vs refused interviews
Each consulate's bar pair shows the percentage of approved (left) vs refused (right) interviews containing the "Why this university / course / program?" question family. Refused frequency is higher at every consulate.
CHART 05Funding Question Subtypes
Funding is the most-tested category in any F1 interview. But within funding, the specific subtype matters. "Who is sponsoring you?" dominates at 30.1%, followed by "Annual income?" at 17.4% — a question that appears in only 3% of approved Kolkata interviews but 12% of refused Kolkata interviews.
Funding question subtypes by frequency
Within the broader Funding & Sponsorship category, individual question subtypes vary widely in frequency. Sponsor identification is the most common; tuition cost the rarest.
CHART 06Q-A Pair Distribution
How many distinct question-answer exchanges does a typical F1 interview contain? The dataset shows a clear bell curve centered at 6-12 exchanges, with the median interview containing approximately 9 Q-A pairs.
Q-A pairs per interview — distribution
Most F1 interviews involve 6-12 distinct question-answer exchanges. Very short interviews (0-2 exchanges) often correspond to fast approvals or fast refusals; very long interviews (17+) often correspond to thorough Hyderabad-style funding-chain probes.
KEY FINDINGSFive Patterns That Decide F1 Cases
"Why this university?" appears in 29.8% of refused interviews vs 19.3% of approved — the largest single-question gap in the dataset. It is the only question that clusters in refusals at all five consulates simultaneously.
"What does your father do?" appears in 30% of all Mumbai interviews — the highest single-question rate of any Indian consulate. Mumbai's decision-making is funding-first; weak funding answers rarely recover later in the interview.
Hyderabad has the highest funding question rate (75.1% of approved interviews) and the highest dataset approval rate (92.2%). Hyderabad officers ask more questions when the case is going well, not fewer — meaning thorough preparation rewards rather than penalizes.
Chennai is the only consulate where Career & Return questions appear at meaningful frequency (14.8%). Chennai officers test whether past, present, and future align — and refuse when the narrative breaks coherence between academic profile and stated career goal.
"Who is sponsoring you?" is the single most refusal-clustered funding question across 4 of 5 consulates. Vague sponsor identification ("my parents") fails; specific identification (named primary sponsor + amount + bank) succeeds. The funding chain matters more than the funding amount.
Practice with the same data that informs these insights
Mainaka's free AI mock interview is calibrated on the canonical dataset visualized above. The mock asks questions the way each Indian consulate actually asks them — and reacts to weak answers the way real officers do.
