Exam-day anxiety changes your I-693 results. Cortisol and adrenaline (stress hormones) raise blood pressure, heart rate and blood sugar. So the reading taken under stress is not your true baseline. A high reading does not mean denial. That is because hypertension (high blood pressure) is not a ground of inadmissibility.
Your anxiety isn’t only a feeling. It’s a physiological event (a body event), and it shows up in your numbers.
Can anxiety raise my blood pressure at the immigration medical exam?
Applicants walk into the clinic with blood pressure raised purely by the weight of the day. They are sure a high reading means denial. It doesn’t. Hypertension is not a ground of inadmissibility. But acute stress (stress in the moment) truly moves the data. Cortisol and adrenaline raise blood pressure, speed up heart rate, and raise blood sugar. The snapshot taken under stress isn’t your true baseline.
How can I stay calm before my I-693 exam?
The goal of preparation is simple. Make exam-day numbers show who you really are. Sleep normally the two nights before. Keep caffeine modest that morning. Arrive early enough that you’re not flooding your body with the adrenaline of running late. In the waiting room, try slow exhale breathing. Breathe out longer than you breathe in. It measurably calms the autonomic stress response (your body’s automatic alarm system) within minutes.
A Physician’s Perspective
Dr. Gurpreet Singh Padda, MD, MBA, MHP does civil surgeon work. Alongside it, he practices metabolic and interventional medicine. The pattern is consistent. The applicants with the calmest bodies aren’t the healthiest. They’re the best prepared. Preparation isn’t just a folder of records. It’s a body that shows up at baseline.

Frequently Asked Questions
Will high blood pressure at the exam hurt my application?
Hypertension is not a ground of inadmissibility. A high stress reading is common and can be repeated. Preparing your body helps the data show your true baseline.
What should I do the morning of my exam?
Sleep normally beforehand. Keep caffeine modest. Arrive early. Use slow-exhale breathing while you wait. These simple steps calm the body. That measurably improves readings.
Does stress affect blood test results too?
Acute stress can briefly raise blood glucose (blood sugar) and other markers. That is another reason a calm, prepared arrival helps your file.
Why is my blood pressure higher at the immigration exam than at home?
Acute stress moves the numbers. On exam day, cortisol and adrenaline raise blood pressure, speed up heart rate and raise blood sugar. So the snapshot taken under stress is not your true baseline. Many applicants arrive with blood pressure raised purely by the weight of the day. Hypertension is not a ground of inadmissibility.
Should I drink coffee before my I-693 exam?
Keep caffeine modest that morning. The goal is exam-day numbers that show who you really are. Sleep normally the two nights before. Keep coffee light. Arrive early enough that you are not flooding your body with the adrenaline of running late. Each step helps your readings show your baseline, not your panic.
What breathing exercise helps before a medical exam?
Use slow exhale breathing in the waiting room. Breathe out for longer than you breathe in. This measurably calms the autonomic stress response within minutes. Add normal sleep, modest caffeine and an early arrival. Together they help your blood pressure, heart rate and blood sugar readings show your true baseline.
